Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. Sometimes, a less expensive imitator of chrome may be used for aesthetic purposes.
Proper control of various plating parameters result in bright, hard, adherent deposits. Chemistry. Practical industrial hard chrome plating baths now in common use have only two or three chemical constituents. Chromic acid is formed when chromium trioxide crystals are dissolved in water. Some form of catalyst is also necessary for the process ...
Hard Chrome Plating is an electrolytic process utilizing a chromic acid based electrolyte; the part is made the cathode and, with the passage of a DC current via lead anodes, chromium metal builds on the component surface including stainless steels and cast irons.
Hard chrome plating is commonly applied to various types of steel and is almost always thicker than decorative chrome plating. Hard Chrome Plating ( Industrial hard Chrome ) : Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Thickness of hard chrome plating ranges from 2 to 250µm.
Chrome plating is an electrolytic process that can be applied to regular steel, stainless steel, aluminum, and other materials. This report details the application of chrome plating to various steel surfaces. 3.0 Types of Chrome Plating There are two basic types of chrome plating: hard chrome plating and thin dense chrome plating.
What is Aluminum Anodizing? Aluminum anodizing is an electrochemical process in which an oxide (anodic) layer is chemically built on the surface of the metal. This oxide layer acts as an insulator and can be dyed in a wide variety of colors. Anodizing provides surface corrosion protection along with an excellent substrate for decorative finishes.
Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Thickness of hard chrome plating ranges from 2 to 250µm. Various types of hard chrome include micro-cracked chromium, micro-porous chromium, porous chromium and crack free chromium.
A.Introduction of hard chrome plating equipment technical process: Hard chrome plating equipment used for plating a layer of thick chrome film on various kinds of base material, which its thickness normally above 20μm, by mean of this, to make use of chromium character to improve plating parts hardness, wear resistance, thermostability, anti-corrosion performance.
1. Hard Chrome or engineered chrome plating. Most people likely do not understand the hard chrome or engineered chrome plating process. Hard chrome plating is applied as a heavy coating for greater lubricity, oil retention, wear resistance and other durability purposes. it is used on such things as piston rings, thread guides, mold surfaces and hydraulic cylinder rods.
