Powder metallurgy (Fig. 5.1) USES sintering process for making various parts out of metal powder. The metal powder is compacted by placing in a closed metal cavity (the die) under pressure.
The effect of hot pressing sintering temperature, pressure and time on its properties are investigated by means of orthogonality rejection and variance analysis.
采用正交设计和方差分析的方法研究了热压烧结温度、压力、时间对该砂轮性能的影响。
