热处理是机械制造的基础工艺,直接影响产品质量。国外对热处理技术一向十分重视,大多实行工艺技术保密,以确保其优质产品的地位。我国自解放以来,热处理技术有了很大发展,一般的工艺、设备以及测试手段基本齐备,热处理生产具有一定规模。在一些基础理论和某些新工艺、新设备及单项 Heat treatment is the basic process of mechanical manufacturing, a direct impact on product quality. Foreign heat treatment technology has always attached great importance to the implementation of technology secrecy, in order to ensure the status of its quality products. Since the liberation of our country, heat treatment technology has made great progress, the general process, equipment and testing methods are basically complete, heat treatment production has a certain scale. In some basic theory and some new technology, new equipment and individual
