Electroplating is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Improve wear resistance, electrical conductivity, reflectivity, corrosion resistance, and enhance aesthetics. The outer layers of many coins are also electroplated.
Blackening is a common method of chemical surface treatment, a method of steel surface treatment. The function is to use the chemical reaction method to form a tight protective film on the steel parts to prevent the spring sheet from being corroded.
There are two ways of blackening, Black Oxide treatment and phosphating treatment. The two blackening treatments have low cost and high production efficiency. We detail the differences between these two processes in this article.
Anodizing is one of the methods of metal surface treatment. Most metal materials (such as stainless steel, zinc alloy, aluminum alloy, magnesium alloy, copper alloy, and titanium alloy) can be anodized in a suitable electrolyte, and electroplating is one of the surface treatment methods for metals and non-metals; All kinds of metal substrates and some non-metallic materials can be electroplated as long as they undergo reasonable pretreatment (for example, ordinary leaves can also be electroplated with suitable pretreatment).
The heat treatment process generally includes three functions heating, heat preservation and cooling, and sometimes there are only two processes of heating and cooling. These processes are interconnected and uninterrupted. Metal heat treatment process can be roughly divided into overall heat treatment, surface heat treatment, local heat treatment and chemical heat treatment.
Changing the steel properties can make the steel easier for the machine. Usually, we do some additional treatments and processes before the machining is complete. Hardening the material before machining increases machining time and tool wear, but steel can be treated after machining to increase the strength or hardness of the finished product. The following are 3 common processing techniques for steel.
Aluminum alloys are easy to process, rich in surface treatment methods, and have good visual effects. They are widely used in notebook computers, mobile phones, portable solid-state drives PSSD, LED desk lamps, cameras, and other products. It is often combined with surface treatment processes such as polishing, wire drawing, sandblasting, high-gloss cutting, and anodizing to make the products present different textures.
Anodizing is an electrolytic process that deposits a chemically stable oxide layer on aluminum surfaces. The resulting oxide film is thicker and stronger than the native oxide coating of aluminum. It is hard, porous, and transparent, making it an integral part of metal surfaces so it will not peel or peel. Once deposited, the oxide film can be coloured in several ways before sealing.
