Title: High strength alloy with resistance to corrosion and wear
Inventor: TAKAHASHI SAKAE
IPC: C22C27/04
Filed: 1997-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain an alloy material excellent in corrosion resistance and wear resistance, having high strength, and suitably used as a material for component parts of a plastic molding machine by adding specific amounts of W, Ta, and B to Ni. SOLUTION: This alloy has a composition in which the content of (W+Ta) is 60-80% by weight ratio and the content of Ta is regulated to a value ranging from 0.6 to 40% based on the content of W and, further, B is contained so that the value of B/(W+Ta) becomes 0.6-1.2 by atomic ratio and the balance is composed essentially of Ni. W and Ta are allowed to react with B and Ni to form a fine double boride Ni (W, Ta)2 B2 at the time of high temp. sintering and improve corrosion resistance as well as hardness and deflective strength of the alloy. Hardness is deteriorated when the content of (W+Ta) is less than 60%, and also coercive force is deteriorated rapidly when it exceeds 80%. The hardness and strength of the alloy are improved by the addition of Ta.  Ta begins to produce the above effect when its additive quantity reaches 0.6% based on the content of W, but, on the contrary, strength becomes deteriorated when the additive quantity of Ta exceeds 40%.
