Abstract

A CORROSION-RESISTANT TUNGSTEN BASED SINTERED ALLOY CAN BE EMPLOYED AS SUCH WITHOUT ADDITIONAL PROTECTION SUCH AS A NI PLATING, DUE TO ITS IMPROVED CORROSION RESISTANCE UNDER A HIGH TEMPERATURE AND HIGH HUMIDITY. THE CORROSION-RESISTANT TUNGSTEN BASED SINTERED ALLOY CONSISTS OF 80 TO 97 PERCENT BY WEIGHT OF W, AND A REMAINDER OF NI, CO, FE AND UNAVOIDABLE IMPURITIES. A COMPOSITION OF AN NI-CO OR NI-CO-FE BINDER PHASE IS FORMED BY 10 TO 98 PERCENT BY WEIGHT OF NI, 2 TO 90 PERCENT BY WEIGHT OF CO AND 0 TO 70 PERCENT BY WEIGHT OF FE IN THE RATIOS OF NI, CO AND FE. THIS CORROSION-RESISTANT TUNGSTEN BASED SINTERED ALLOY IS PREPARED BY LIQUID-PHASE SINTERING A MIXED POWDER OF THE AFOREMENTIONED COMPOSITION IN A REDUCING ATMOSPHERE AT A TEMPERATURE THAT IS 10 TO 80°C HIGHER THAN THE MELTING TEMPERATURE OF THE BINDER PHASE.
