Abstract
PURPOSE:To give a creepproof and omissionproof property, by constituting with a sliding layer forming the surface to which a valve is touched in a sliding manner and a base layer which supports the sliding layer, both of which are provided with mixed powder consisting of special alloy powder, graphite powder and ferrous powder. CONSTITUTION:A cast iron made cylindrical jig 2 is provided with a steplike part for insertion of a testing valve seat 1 on the upper part of an inner wall. The testing valve seat 1 consists of a sliding layer 1a and a base layer 1b. Special alloy powder contained in mixed powder for sliding layer contains 2% of C, 8% of Ni, 20% of Mo, 34% of Co and 2% of Nb in wt% and the remainder is formed of Fe. To make this special alloy powder, a metal mixture is melted in a high frequency induction furnace and founded in a plate which is pulverized by a stamp mill and is made into powder of 150 mesh through sifting. Quantities to be used for the mixed powder for the sliding layer and the mixed powder for the base layer are made so that a ratio between thicknesses of the sliding layer and the base layer becomes 4:6.
