摘 要

厨刀是我们生活中不可或缺的工具之一，通常采用不锈钢作为原材料。近年来，随着厨刀行业的不断发展，对厨刀质量问题的研究探讨成为了重中之重。本文采用热处理炉、光学显微镜、显微硬度计、洛氏硬度计等仪器对厨刀用马氏体不锈钢进行了热处理及性能研究。

论文主要内容是对厨刀用1.4116马氏体不锈钢进行的一系列热处理工艺，并对其性能进行了研究。通过对结论的分析，找出最适合的热处理工艺条件，通过最优的热处理工艺来提高厨刀的性能，解决厨刀在使用过程中可能遇到的一系列问题，比如腐蚀，刀刃钝化等等，延长其使用寿命。通过研究得到以下结果：1.4116马氏体不锈钢的最佳热处理工艺参数为：1030℃×30min，深冷处理，100℃×2h回火，空冷处理。

关键词：1.4116马氏体不锈钢；热处理工艺；深冷处理；性能研究

Abstract

Kitchen knife is one of the indispensable tools in our life, usually using stainless steel as raw materials. In recent years, with the continuous development of the kitchen knife industry, the research on the quality of kitchen knives has become a top priority. In this paper, the heat treatment and properties of martensite stainless steel for kitchen knives were studied by means of heat treatment furnace, optical microscope, microhardness tester and rockwell hardness tester.

The main content of this paper is a series of heat treatment process of 1.4116 martensitic stainless steel used for kitchen knives, and its properties are studied. Through the analysis of the conclusion, find out the most suitable heat treatment process conditions, through the optimal heat treatment process to improve the performance of kitchen knives, kitchen knives in the use process may encounter a series of problems, such as corrosion, blade passivation, and so on, to extend its service life. The optimal heat treatment parameters of martensite stainless steel are: 1030℃×30min, cryogenic treatment, 100℃×2h tempering, and air cooling treatment.

Key Words：1.4116 martensitic stainless steel; Heat treatment process; Cryogenic treatment; Performance study
