Abstract: PURPOSE:To obtain the titled valve seat material with enhanced heat resistance and fatigue strength by sintering temporarily a sintered alloy valve mating material consisting of a layer on the valve-contact surface side and a layer on the head seat surface side, and infiltrating copper into the valve-contact surface in a converted gas atmosphere. CONSTITUTION:A layer on the head seat surface side consisting of 11-15%, by weight, Cr, 0.4-2.0% Mo, 0.05-0.3% C, and the remainder of Fe and impurities and a layer on the valve-contact surface side consisting of 4-8% Co, 0.5-1.5% Cr, 4-8% Mo, 1-3% Ni, 0.3-1.5% C, 0.2-0.6% Ca, and the remainder of Fe and impurities are sintered to obtain a united body. The two-layered sintered body is treated with copper infiltration at 1,100-1,150 deg.C in a converted gas atmosphere, and only the layer on the valve-contact surface side is infiltrated with copper. Consequently, a sintered alloy valve mating material having high extracting load and excellent resistance to heat and creep can be obtained.

IPC: G06F17/50
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To easily calculate a gap between two line patterns regardless of their shapes by calculating four distances between both end points of each stroke belonging to one of both line patterns and both end points of each stroke belonging to the other line pattern. SOLUTION: The center lines L1 and L2 of two line patterns are divided into strokes L11 to L1n and L21 to L2n respectively, so that these strokes have lengths smaller than a prescribed value and also are identical to the straight lines or curves including no corner parts. Then, four distances are calculated between both end points of each of strokes L11 to L1n belonging to one of both line patterns and both end points of each of strokes L21 to L2n belonging to the other line pattern. The strokes L1a and L2b which are closest to each other and form the shortest one of those four calculated distances are decided. This operation is repeated to calculate the final shortest distance for the m-th stroke, and the value decided by subtracting the double as much as the edge part width from the shortest distance is defined as the smallest gap between both line patterns.
