Powder overlay welding was performed using an alloy, a Co-based alloy, an l''e-based alloy, or particles made of these alloys mixed with WC particles as an overlay material to form an overlay layer in which the WC particles were dispersed and settled. This is a manufacturing method of a wear-resistant composite material in which the surface layer portion of the built-up layer where WC particles have settled and decreased is then removed and the inner layer enriched with WC particles is used.Then, the above alloy is For example, conventionally known ingredients as shown in Table 2 are used.

It has settled to . The abrasive wear test was performed to examine the wear resistance by removing the areas on the surface of the built-up layer where WC particles had decreased. In the abrasive wear test, the test piece is rotated, pressed against abrasive paper under a constant load, and the wear loss is measured when the test piece is fed sideways, and the test conditions are as shown in Table 4. The test piece has a diameter of 5 mm and a length of 30 I.
It has a round bar shape. Table 5 shows conventional materials with high wear resistance and corrosion resistance used as comparative examples: Ni-Co-cr-B
