Semiconductor Silicone Materials Semiconductor Silicone Materials – Essential to Semiconductor Fabriion When it comes to materials used to manufacture semiconductors, most people are familiar with copper, but there are a nuer of silicone materials that are essential to key processes such as chemical vapor deposition (CVD)/atomic layer deposition (ALD) gas/precursor, and spin-on
Tungsten carbide coating and sprays have increasingly become the most preferred method for improving or salvaging components. Thermal spraying is a process of coating that involves spraying melted materials onto the surface of another component with the aim of coating it.

Nickel - Electroless - A Class Metal Finishers
Additives such as Teflon or Silicon Carbide can be included into the deposit to further increase the properties such as lubricity and wear resistance. Can (like hardchrome) be machined. However, THE REQUIREMENT TO MACHINE BACK TO TOLERANCES IS OFTEN ELIMINATED by the ability to apply the nickel coating uniformly and in thicknesses that can maintain tolerances to within approx 10 mil.
Electroless Nickel PTFE is a slick composite Nickel/PTFE coating that gives a low coefficient of friction without undermining the cohesion and the relative hardness of the coating. The particle size of the PTFE has been reduced to sub-micron spheres, achieving the optimum % content and even distribution.

Silicon Carbide is used in many industries and much of it can be recycled. Weather you are in the aerospace industry and use silicon carbide to polish parts or building armor plaiting for the military we can help you recycle
Abstract A process is described for forming silicon carbide coatings on nickel based superalloys by: i) nitriding the alloy or depositing a titanium nitride film on the alloy by reactive sputtering; ii) vapour phase chemica deposition of a thin film of titanium nitride; iii
Electrodeposition of nickel/silicon carbide composite …
Composite coatings suitable for protection against wear were prepared by electrodeposition from a nickel Watts solution containing silicon carbide particles maintained in suspension. To obtain a better understanding of hydrodynamic effects on the codeposition process a rotating disc electrode, immersed in a vertical rising flow, was used.

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
