Abstract
The invention relates to a plasma surfacing method and further relates to application of products manufactured by the application of the method. The method comprises the following steps that (a), nickel base metal powder and diamond powder are mixed; (b), the mixed powder is placed on the surface of a matrix through plasma surfacing, preferably, the mixed powder comprises, by weight, 96-99 parts of the nickel base metal powder, 1-4 parts of the diamond powder, or 98 parts of the nickel base metal powder and 2 parts of the diamond powder. The products manufactured by the method for the plasma surfacing diamond abrasion-resisting layer have the advantages of being high in abrasion performance, high in hardness, high in impact resistance, free of tungsten carbide and low in cost. The advantages of lower cost and higher intensity are provided due to the weight proportion and fineness of raw materials. The cost is lower due to the use of plating diamonds.
