由于低合金钢试样的渗碳层深度并不总是与成品零件的渗碳层深度一致,所以,本文就如何更精确地控制8620和8822钢件的渗碳层深度提出了一种见解。现代制造工艺中,在渗碳热处理方面,对工件的一些重要部位,例如齿轮的齿合部位,几乎总是规定了一定的渗碳硬化深度。这是一项很重要的工艺要求。渗层深度一般是指从表面到内层硬度为HRC50处的垂直距离。这种提法,显然是对成品而言,而不是指单独的试样。但是,剖开零件测其渗层深度,不仅代价很高,而且往往是不可能的,例 Since the depth of carburized layer in the low-alloy steel specimen is not always the same as the carburized depth of the finished part, this paper presents a view on how to control the carburized depth of 8620 and 8822 steel more precisely. In the modern manufacturing process, some important parts of the workpiece, such as the toothed part of the gear, almost always stipulate a certain depth of carburization and hardening in the carburizing heat treatment. This is a very important process requirement. Penetration depth generally refers to the vertical distance from the surface to the inner hardness of HRC50. This formulation, apparently for the finished product, rather than a separate sample. However, it is not only costly but often impossible to cut open the part to determine its depth of penetration
