Coatings: Wear Resistant related categories
 | Black Codiac Coatings
BLACK CODIAC produces two distinguishable microstructural zones: a shallow, hard ductile surface case made up of epsilon iron nitride and, beneath it a relatively deep diffusion layer, which is essentially nitrogen in solid solution.
The surface, or compound layer contains compounds of iron, oxygen, 7-9% nitrogen and approximately 1% carbon. This intermetallic iron-nitride compound forms during the diffusion of atomic nitrogen when the solubility of nitrogen at the surface is exceeded. The nitriding potential of the Black Codiac bath is designed and controlled to produce a specific nitride, i.e. epsilon iron nitride, Fe3N, which is the predominant phase in the compound zone. Thickness of the compound zone depends primarily on treatment time and the carbon and alloy content of the base material: the higher the carbon and/or alloy content, the thinner the reactive area. However, the average Black Codiac cycle produces a compound layer .0004′′ to .0008′′ deep.
The compound layer is highly resistant to wear, seizure and corrosion. It is durable practically up to the temperature at which it was generated and has a room temperature hardness in the range of HV 550-1000, depending on the material.
Typically, the nitrogen penetrates the ferrous matrix to a depth of .020′′ to .040′′ to form the diffusion zone. Both depth and hardness are heavily influenced by the material: the higher the nitride-forming element content of the steel, the lower the nitrogen penetration, given equal processing time. Unalloyed steels which are cooled slowly or reheated after processing may experience some nitrogen precipitation from solid solution, thus forming needles of gamma prime iron nitride, Fe4N, in the nitrogen-rich region of the diffusion layer. The total nitriding depth will be approximately two to three times as deep as the needle depth, depending on the material. |
 | Codiac Coatings
Composite Diamond Coating (CODIAC) is a regenerative layer of an electrolessly plated matrix, usually a nickel/phosphorus alloy, with finely divided particles uniformly dispersed in it. The particles are uniform in size, and range from 0.1 to 10 microns. Coatings may contain up to 50% diamond by volume, though standard diamond content is in the 20 to 30% range. The nickel matrix alloy most commonly used is made up of 90-93% nickel and 7-10% phosphorus. |
 | Microlon 1010 Coatings
This resin matrix bonded coating provides the optimum combination of wear resistance, low coefficient of friction, and excellent nonstick (AKA ′′release′′). Microlon 1010 is unaffected by or resistant to most chemicals and corrosive agents. It has an operating temperature to 500°F (260°C) continuous and 600°F (315°C) intermittent.
Microlon 1010 is an excellent lubricant and can withstand loads up to 50,000 psi. For this reason it has been successfully used in the automotive industry on pistons, rocker arms, wrist pins and other bearing surface applications. It may be used to prevent scoring and galling, or provide secondary lubrication due to the failure of the primary (conventional) lubricant. Additionally, Microlon 1010 has good abrasion resistance and therefore, may be used to solve varying problems from release to friction reduction. |
 | Microlon 2610 Coatings
Microlon 2610 is a resin-bonded dry film lubricant which is used to a variety of industrial and consumer applications. The coating is a codispersion of molybdenum disulfide (MoS2) and a matrix of other lubricants in a thermosetting resin solution. Microlon 2610 is designed to produce a tough, low friction coating with high wear resistance and is capable of withstanding continuous service temperatures of up to 500°F (260°C).
Microlon 2610 provides exceptional lubricity and wear resistance for metal to metal applications. It can be applied to any metal surface and may be combined with a zinc phosphate pretreatment for added corrosion resistance and better wear properties. |
