A Simple Overview Of Zinc Electroplating

A Simple Overview Of Zinc Electroplating
Zinc plating is one of the lowest cost, most effective options in electroplating for parts and components in a wide variety of industries. Also known as galvanization, zinc electroplating can be done quickly, effectively and with high levels of precision across any surface, including complex surfaces of various shapes and configurations. As with any type of surface finishing and plating process, there are several steps involved in zinc plating. Each step has to be done correctly as it has a direct impact on the final product. Often less experienced electroplating companies do not take the time to ensure each step in the process is correct, which results in incomplete or irregular plating or failure of the plating at a later point in time. Surface Prep It is critical for all surface oils, grease, chemicals and oxides that may be present on the metal. The cleaning involves placing the part in an alkaline solution and then into a weak acid. The alkaline cleans the surface of residue, and the acid etches the surface to allow more effective plating. Zinc Plating Methods The process of zinc electroplating is considered to be a bio-friendly method. It does not use highly toxic cadmium, which was used prior to the 1980s. In some cases, cadmium is still considered the best choice, but it is no longer a common plating option. To complete the zinc electroplating process, the metal is placed into a specially designed electrolyte solution. This can be either acid or alkaline and needs to be carefully formulated to provide both thickness distribution and ductility of the surface. The material, in the electrolyte solution, is then exposed to an electrical current. The part forms the cathode and as the current passes from the anode through the solution and creates the plating on the surface. After completed, the parts are rinsed and dried and may go through passivation or the application of a coating for further durability. 2 people like this...

Rack Plating or Barrel Plating?

Rack Plating or Barrel Plating?
Today, many kinds of metal materials receive a protective coating with a process known as electroplating. Some companies use barrel plating methods while others prefer rack plating, or they may use both. There are specific benefits to each process, and it is important to know them so that you can get the best materials and parts for your business. Here is information on both processes for your consideration. Barrel Coating Barrel coating or plating refers to putting parts inside a plastic barrel. Inside the barrel are conductive metal bars and electricity passes through them and the plating solution in the barrel. A machine rotates the barrel and as it slowly spins the parts receive an even coating. This is similar to the way clothing moves about inside a clothes dryer. Barrel plating is a good way to protect parts from corrosion with a protective coating. It also produces a shiny and attractive finish. Coated parts last longer because they receive less wear and tear. Rack Plating Metal parts get placed on racks, and are tightly secured in place. With rack coating, parts do not spin or rotate during the coating process. They remain stationary as they lower into the plating solution. Barrel Coating Pros and Cons Barrel coating requires less expensive equipment than rack coating methods. There is less labor required too. This lets you offer the customer lower priced parts and materials. Yet, this method does not give you a high-quality finish. Rack Coating Pros and Cons Rack plating requires special racks and some of them are custom designed and manufactured. It takes a lot of time and labor to produce parts. This can add to the cost of the process. However, you can coat intricate and large parts this way and give them a quality finish. Both rack and barrel methods work well on many types of metals. 1 person likes this post. Like...

Allvac 718: A Popular Super Alloy

Allvac 718: A Popular Super Alloy
When the product must function without problems at a minimum of 1000ºF, (540ºC) fabricators turn to a group of metals called the super or high-performance alloys. They provide the requisite high surface stability as well as resistance to deformation demanded from such applications. They also boast several other characteristics that make them almost ideal for the aerospace industry and cryogenic industries. Among the various superalloys is Allvac 718. What Is Allvac 718? This specific alloy is a member of the Inconel family of alloys. It mainly consists of two metals: nickel and chromium. However, it also contains relatively high levels of iron, niobium, and molybdenum as well as lesser quantities of aluminum and titanium. The result is an alloy with various qualities and properties. Fabricators utilize this particular alloy for the following reasons: Excellent mechanical properties Easy for use in fabrication Good workability – both hot and cold High corrosion resistance Excellent strength Temperature resistance Highest level of weldability and very resistant to post-weld cracking What fabricators and manufacturers alike also find attractive is the moderate cost of the alloy. Typical Applications Companies find this Inconel alloy desirable for use in diverse applications. Below are some of the major applications: Blowout preventers Castings for cryogenic applications High-speed airframe castings Fasteners for fire-safe valves Jet engine castings Land-based gas turbine castings Nuclear reactor component castings Oil field castings Packers Pumps Rocket motor castings Spacecraft Side pocket mandrels Subsurface safety valves Valve gates Valve seals Valve seats Valve stems Well logging casing Allvac is particularly popular for use in castings for the aerospace industry. Allvac 718 Allvac 718, a member of the Inconel family of alloys, remains popular in the aerospace industry. Recently, however, researchers have increased the capabilities of this superalloy. The result is ALLVAC 718 Plus™. This new alloy exhibits higher levels of those properties that make Allvac 718 popular including tensile strength and resistance to both corrosion and oxidation.

The Metal Fabrication Companies St. Paul, MN Offers Help to Keep Older Aircraft in Service

Many small aircraft built forty, fifty, or more years ago are still providing safe, reliable service. The unique nature of small airplanes means that their frames can often go decades without suffering the kinds of stresses that would ground them permanently. At the same time, keeping a small aircraft regularly aloft over the course of many years does require plenty in the way of attention and maintenance. Particularly insofar as many craft of this class have been out of production for so long, the Metal Fabrication Companies St. Paul MN hosts often play an important role in this process. The reason for this, of course, is simply that manufacturer-produced replacement parts are often no longer available. Whether an entire control surface needs to be replaced or a simple metal shim has failed and must be procured, the Metal Fabrication Companies St. Paul MN has to offer often provide help that allows the owners of smaller aircraft to keep their beloved possessions in service. The process of working with a company of this kind, like the one at Website Url, tends to be fairly straightforward and simple. In the ideal case, the part to be replaced will be provided to the fabrication specialist, as there is typically no easier way of ensuring that the new one will fit and provide proper service. Even in those cases where the original is no longer available, however, having some accurate measurements made can often be enough to allow for the necessary work to be done. With those basics taken care, a first attempt at the replacement part can generally be turned out. In many cases, this will prove to be worthy with only the act of trying to fit it sufficing to prove whether this is the case. In those situations where the part does not live up to what is required of it, all that will generally be needed will be a bit of adjustment, a process that can take as little as an additional hour. By communicating consistently and accurately with the fabricator in question, an owner of an older airplane can be assured of receiving everything need to keep the craft in service for many rewarding years to come.
