摘要

对磨料、切削和模具金属加工工具的工作进行了比较评价，并制定了对其基本操作性能的要求。揭示了金属加工工具失效的两个主要原因：金属加工工具的脆性断裂和塑性断裂。提出了提高刀具工作能力的方法：(1)热化学处理制备超硬硬质合金涂层；(2)热水化学处理制备固体润滑涂层；(3)体积强化热循环处理。

Operational Evaluation of Metalworking Tools and the Requirements for Them

A comparative evaluation of the work of abrasive, cutting, and die metalworking tools is made, and the requirements for their basic operational properties are formulated. Two main causes for the failure of metalworking tools have been revealed: their brittle and plastic fracture. The following methods of improving the working capacity of tools are proposed: (1) thermochemical treatment for producing superhard carbide coatings, (2) thermohydrochemical treatment for producing solid lubricating coatings, and (3) volume strengthening thermal cyclic treatment.

期刊介绍： Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
