Chrome Carbide High Temperature and Wear Resistant Surfacing Cr3C2 with Binders of Ni/Cr
Chrome carbide coatings are notable for several uses; one of its most significant benefits is its wear resistance in higher temperature environments. Chrome carbide can be an excellent choice as an alternative to tungsten carbide, depending on operating conditions. While chrome carbide has less wear resistance then tungsten carbide, chrome carbide coatings along with a nickel/chrome binder chemistry has heat resistance and oxide resistance characteristics at higher temperatures and under corrosive or oxidizing conditions. The properties of chrome carbide coatings can be further enhanced when the metal alloy matrix is made from nichrome alloy, which has high corrosion resistance. Coatings with chrome carbide are appropriate for applications ranging from 1,000F to 1,500F or 540 C to 815C approximately. We recommend chrome carbide coatings for applications that require resistance for wear by abrasion, hard surfaces, fretting, and particle erosion.
ASB Industries applies chrome carbide coatings by utilizing either one of our HVOF processes or our plasma electric arc process. We decide on which process to use based on part dimension, configuration, and required finishing. These commercially available systems give versatility to defined coating properties based on operating parameters of each of these systems
Chrome Carbide Chemistries
ASB Industries limits our number of material suppliers to focus on material quality and consistent particle range. This allows us to optimize the deposit efficiency for our chrome carbide coatings, whether using plasma electric arc or HVOF processes, and with either gaseous or liquid combustion fuel. Material morphology based on production processes produce different results. ASB Industries will ask you questions based on your application and choose both the process and material to provide an optimized surface. Available material morphology including a nickel/chrome binder matrix manufactured by sintering and crushed, blended, clad, agglomerated, and densified in a spheroidal shape.
Benefits & Uses
Coatings of chrome carbide are recommended for resistance to wear by abrasion, fretting, cavitation, and particle erosion in high temperature applications.
Chrome carbide surfacing resists oxide pick-up in high temperature atmospheres for steel production. This reduces product damage on components that directly contact steel strip and other shapes during high temperature annealing. Turbine components with critical initial testing and proven results under extended and demanding operations make the wear resistance of chrome carbide coatings an ideal solution. Chrome carbide also provides significant benefits in applications where the part would be exposed to environments that move solid particles in erosive gasses by coating the duct work and fan surfaces.
