CT3302-4 is a Nickel Chromium Silicon Boron/ Tungsten Carbide material which, when sprayed with HVOF technology and then fused creates a very wear resistant layer. This layer exhibits better wear resistance in many appliions than would be typical even of another fused coating with the same percentage of tungsten carbide due to the fine particle size of the carbide.
Electroless Nickel Plating | Products Finishing
Nickel Phosphorus. The majority of EN plating is done using nickel phosphorus (Ni-P) systems. These deposits give a low coefficient of friction and are anti-galling. They have superior as-plated hardness and can be further hardened by post-plating heat treatment

the surface. This PCP pre-treatment method was applied to electroless nickel and copper coating of a Teflon substrate , and to Ni-Fe-P layer on carbon nanotubes . The same method was applied to coat boron carbide particles  and nano silicon
Steel vs Nickel Cylinders | Pilots of America
2012/1/8· "" The Nickel+Carbide process is a coating consisting of extremely hard silicon carbide particles in a nickel matrix. The high hardness of the silicon carbide particles effectively prevents wear from occurring throughout the life of the cylinder. "" From my link , 2011
RAM New and Overhauled Nickel Cylinders
The final operation in Nickel+Carbide coating process includes a carefully controlled, 2-step honing procedure so that a “plateau finish” is imparted to the bore surface. As the name implies, the finish consists of plateaus and subsurface valleys, which are essential to the ring break-in process, as well as proper lubriion of the ECi plasma-coated compression ring and bore interface system.

The Silicon Carbide particles stand as little peaks on a microscopic level, while the Nickel holds the peaks together. The two-stroke lube, or the engine oil on four-strokes, sits between these peaks to form a lubriing surface which allows the piston to move easily at high speed.
Thickness Limitation A&A Coatings HVOF Sprayed Tungsten Carbide was designed for use in thin coatings, not more than .5mm (.025″) thick. If sprayed thicker, the probability of cracking and delamination will increase rapidly, as is the case of thick coatings of all
Beta silicon carbide powder widely used in functional ceramic materials. The performance of beta silicon carbide powder: 1. β-SiC powder has a high chemical stability, 2. high hardness, 3. high thermal conductivity, 4. low thermal expansion coefficient,
Role of Silicon Carbide in Phase-Evolution and Oxidation …
Silicon carbide (SiC) was reinforced in the pulse electrodeposited nickel-tungsten (Ni-W) coatings deposited on the steel substrate, and isothermal oxidation test was performed at 1273 K (1000 °C) for 24 hours. Addition of just 2 vol pct of SiC showed 26 pct increase in the relative oxidation resistance of Ni-W coating. The increased oxidation resistance was attributed to the phase evolution
Electroless nickel is a hard, silver coloured coating comprised of nickel alloyed with between 4 and 14% phosphorus. It is deposited by immersion of parts in a solution of nickel salts and reducing agents at a temperature of 90 C. Although it has the appearance of

Nikasil - Wikipedia
Silicon carbide is a very hard ceramic (much harder than steel) that can be dissolved in nickel. The nickel solution can then be electroplated onto the aluminium cylinder bore. The piston rings will then rub off the exposed nickel, leaving a very hard layer of silicon carbide to prevent the cast iron/steel piston rings directly contacting the aluminium cylinder.
Silicon Carbide (SiC) | Morgan Technical Ceramics
Silicon carbide is formed in two ways, reaction bonding and sintering. Each forming method greatly affects the end microstructure. Reaction bonded SiC is made by infiltrating compacts made of mixtures of SiC and carbon with liquid silicon.
