Wear-resisting coating printing press roller with supersonic flame spraying, tungsten carbide coating is better than traditional chilled cast iron roll shows excellent wear resistance.Microhardness of tungsten carbide coatingHV1300, which is equivalent toHRc75And the hard chromium plating and the hardness also can only achieve chilled cast ironHRc65, according to foreign relevant materials, the wear resistance of sprayed tungsten carbide coating for chilled cast iron10Times.Tungsten carbide coating8GPaRolling contact fatigue strength, can withstand the calender roller grinding pressure;Because of the compact coating nonporous, corrosion resistance is superior to plating roller surface;Compact coating can grind to a mirror finish, in the ordinary steel roller coating the surface of the tungsten carbide coating, can avoid the chilled cast iron casting defects.
