                          Cr3C2-Chromium Carbide

                          Surface Coatings

                          线上十大赌游Unlike surface treatment methods whereby the existing surface is changed by diffusion, in surface coating an outer layer of new material is generated on the surface. The following types of surface coating methods are available in the Habonim metal seated range; chromium carbide with nickel chrome binder (Cr3C2), tungsten carbide with cobalt binder (WC-Co), and stellite welding.

                                       

                          线上十大赌游Hard Coating done by HVOF                                       The Hardness is Over 600 HRC

                          Stellite

                          A cobalt-based stellite coating provides excellent mechanical wear resistance, with good corrosion resistance at temperatures up to 538˚C (1000˚F). The Stellite is applied by a Plasma Thermal Arc (PTA) method. Most stellite alloys are cobalt based with elements of Chromium (Cr), Carbon(C), Tungsten (W) and Nickel (Ni). Stellite is broadly used in the pulp and paper industry, as well as in refining applications, such as catalyst handling and hydrocracker processes.

                          WC-Co (Tungsten Carbide)

                          线上十大赌游Tungsten Carbide with a cobalt binder coating applied by HVOF techniques similar to Cr3C2.WC-Co coating applied mainly to 400 series martensitic stainless steel results with micro-hardness as high as 72HRC. This coating resists cryogenic temperature down to -196˚C (-320˚F) and high temperatures up to 538˚C (1000˚F). WC-Co is a wear resistance anddense coating with chemical resistance to sulphur environment on Nickel based alloy.

                          Cr3C2 (Chromium Carbide)

                          线上十大赌游Chromium Carbide with nickel chrome binder applied by a High Velocity Oxygen Fuel (HVOF) gun creates a 0.3mm hard outer layer. Cr3C2 coating applied to high strength steels, results in a micro-hardness of up to 68HRC. This coating resists cryogenic temperatures down to -196˚C (-320˚F) and high temperatures up to 815˚C The valve maximum temperature is 650°C. All the temperatures above 650°C refer to the coating or bolts performance only (1500˚F). This multipurpose wear resistance coating is used extensively in the power generation, refining and hot catalyst handling services. Its limitations are in wet sulphur or chloride environments where sulphuric acid can form and attack the coating.
