摘要： A raw material for powder metallurgy contains at least 0.5 vol % and at most 10 vol % of alumina powder of which the sieve fraction with a sieve opening of 30 .mu.m is at most 0.1 wt %, and a remaining part of aluminum alloy powder. The moisture content of the alumina powder is at most 0.15 wt. % with respect to the alumina powder. Agglomeration of particles is thereby minimized or avoided. Highly reliable raw material for powder metallurgy having superior fatigue strength, impact resistance and wear resistance can be obtained. A method of preparing such a mixed powder raw material involves air classifying the powder materials, dry ball mixing the materials, and then annealing the mixed powder.
摘要翻译：粉末冶金用原料含有至少0.5体积％，最多10体积％的筛孔为30μm以下的筛分级别为0.1重量％以下的氧化铝粉末，剩余部分为铝合金粉末。氧化铝粉末的含水量为0.15重量％以下。相对于氧化铝粉末为％。从而使颗粒的聚集最小化或避免。可以获得具有优异的疲劳强度，耐冲击性和耐磨性的高度可靠的粉末冶金原料。制备这种混合粉末原料的方法包括将粉末材料进行空气分类，将该材料进行干球混合，然后对混合粉末进行退火。

摘要： A lightweight and high-strength valve lifter is excellent in wear resistance and sliding properties. The valve lifter is made of a titanium alloy having a hardened layer on the top surface thereof, on which a cam is caused to slide. The hardened layer is composed of an α-case and an oxygen diffusion layer under the α-case. The α-case 22 is formed in a thickness of not less than 3 μm and not more than 15 μm. The oxygen diffusion layer has a thickness of not less than 10 μm. The hardened layer on the top surface of the valve lifter is formed by oxidation treatment in a furnace at a temperature of not less than 600° C. An outermost oxide layer 21 formed on the α-case as a result of the oxidation treatment is removed.

摘要： A valve lifter and a method of manufacture thereof is provided in which sliding properties of a cam on a cam-contacting sliding surface in an upper surface of a valve lifter are improved by forming the cam-contacting sliding surface as a concave surface to permit retention of lubricating oil therein. The cam-contacting sliding surface is integrally provided in an outer wall of an upper part of a valve lifter. The cam-contacting sliding surface is formed as a concave surface to provide better retention of the lubricating oil. The concave sliding surface is formed during high temperature oxidation of the valve lifter by permitting the natural slumping down of the upper part due to its own weight under the gravity.
