摘要
采用金属粉末注射成形(MIM)工艺制作几何形状复杂的小型金属零件,尤其是针对具有多数特征重复且相似的传动零件有一定的优势,例如常见的小模数齿轮.采用不锈钢17-4PH作为MIM技术的金属齿轮材料,这种材料的机械性能和防腐蚀能力优于传统机械加工齿轮的材料.实验按照不锈钢17-4PH的特性,以MIM工艺制作齿轮并对其进行不同条件的热处理(烧结后、H900、H900后+退火),经质量测试后呈现微小的变化,与传统热轧板材结果相近,MIM工艺可制作复杂齿轮并保持不锈钢17-4PH优良的尺寸精度,并能够提升机械性能.
Abstract
The use of metal powder injection molding(MIM)technology to produce small metal parts with com-plex geometric shapes,especially for transmission parts with similar and repeated features,such as small module gears,had certain advantages.As for the selection of metal gear materials,stainless steel 17-4PH could be used in-stead of MIM technology.The mechanical properties and corrosion resistance of this material are superior to those of traditional machined gears.In this paper,according to the characteristics of stainless steel 17-4PH,gears were made by MIM process and heat treated under different conditions(after sintering,H900,H900+annealing).After quality testing,there is a slight change,which is similar to the results of traditional hot rolled plates.MIM process could make complex gears,maintain the excellent dimensional accuracy of stainless steel 17-4PH,and improve me-chanical properties.
