渗碳,作为提高零件的强度、硬度、耐磨性、从而达到延长使用寿命的一种新技术被广泛地应用。对渗碳质量的要求,其中之一就是渗碳层深度。生产中对渗碳层的检验,据了解,一律按图纸要求,有的厂,对于低于图纸要求的,既使是少一丝,都要进行补渗,反之,对超深件的处理,那怕是仅超深一丝,都将其报废,可谓对质量“一丝不苟”,要求严矣!然而,由于我们金相工作者在制样过程或热处理工人在操作时,由于一时疏忽,或未能严格按技术要求办,所造成的差错远远超过一丝。为了正确反映渗碳层深度,现将测定渗碳层深度应注意的几个问题叙述如下:
Carburizing, as a new technology to improve the strength, hardness and wear resistance of parts, so as to prolong the service life, is widely used. One of the requirements for the quality of carburizing is the depth of the carburized layer. Production of carburized layer test, it is understood that all drawings required, and some plants, less than the drawings required, even a trace of less, have to make infiltration, on the contrary, the handling of ultra-deep pieces, that However, because our metallurgical workers in the sample preparation process or heat treatment workers in operation, due to temporary negligence, or not strictly According to the technical requirements to do, the errors caused by far more than a hint. In order to correctly reflect the depth of carburized layer, the depth of carburized layer will now be measured to note several issues described below:
