摘要
The chapter discusses issues of improving the efficiency of honing in machining low-carbon complex alloyed steels. The disadvantages of honing "soft" stainless steel 12H18N10T (AISI 321) and frost-resistant steel 09G2S are given. The known methods of increasing the surface hardness such as nitriding, carburization, ni-carbing, hydrogen absorption, and laser alloying of the surface layer have been considered. However, the known chemical methods of increasing the surface hardness have common disadvantages, i.e., reduced corrosion resistance of products that is especially important for the chemical and food industry, as well as thermal deformations of large-sized products arising from the distribution of internal stresses due to heating to temperatures of 700-950 degrees C. Therefore, these methods are not applicable in some cases. The well-known method of increasing the surface hardness and strength of products made of hardened steels is the plastic deformation, carried out, for example, by rolling or burnishing. For this reason, we propose a new processing method. This is honing with prior plastic deformation.
