Cutter, composite material thereof and preparation method of composite material

Abstract

The invention discloses a cutter, a composite material thereof and a preparation method of the composite material. The preparation method of the composite material includes the steps of material preparation; performing surface treatment on the joint face of a composite layer; tightly closing a core layer to the composite layer and forming a to-be-machined body in a sealing manner; when the to-be-machined body is heated to a composite fusion welding temperature, the surface of the composite layer of the to-be-machined body is slightly knocked; at a composite forging temperature, the to-be-machined body is subjected to deformation treatment; and the to-be-machined body after deformation treatment is subjected to heat treatment. The composite material of the cutter is made according to the preparation method, and the cutter is made according to the composite material. The preparation method solves the problem that combination of stainless steel and plain carbon steel is difficult, the composite material obtained through the preparation method of the composite material has good rust preventing function, large hardness and toughness is achieved, and the cutter made from the composite material has good rust preventing function; and meanwhile, a cutting edge is large in hardness, a cutter body is good in toughness, the cutting edge is not likely to generate a notch and cutting edge curving, re-grinding performance is good, and use by a user is convenient.

Description

technical field [0001] The invention relates to the field of cutting tool materials, in particular to a cutting tool, its composite material and a preparation method of the composite material. Background technique [0002] Knives are one of the most commonly used and used items in daily life. Ordinary carbon steel knives are prone to rust, which not only affects the appearance, but also excessive intake of rust will cause damage to the human liver, which is not good for personal health. Although stainless steel knives have excellent corrosion resistance, their regrinding properties are poor, and their hardness is not enough, so they are easy to curl. Contents of the invention [0003] The main purpose of the present invention is to provide a cutting tool and its composite material and the preparation method of the composite material, the preparation method solves the problem of difficult combination of stainless steel and carbon steel, and the composite material obtained b...
