Abstract
The method for coating alloy coating layer on steel surface by means of friction process is characterized by that it makes coating alloy whose melting point is less than that of steel to be coated and coated steel implement rapid relative friction under the contact pressure of 10MPa-20MPa so as to make the coating alloy contact surface reach melting point to obtain alloy coating layer.
Description
technical field [0001] The invention belongs to a new method for obtaining an alloy coating on a surface and a new method for obtaining an alloy coating on a steel surface. Background technique [0002] Metal materials can improve the properties of materials such as strength, hardness, wear resistance and corrosion resistance through surface treatment. Most machine parts are surface treated. The surface treatment methods of steel include carburizing, nitriding, surface quenching, physical vapor deposition (PVD), chemical vapor deposition (CVD), high energy beam surface treatment and so on. Among these methods, the methods with the longest history and low cost are carburizing, nitriding and surface hardening. [0003] Methods such as physical vapor deposition (PVD), chemical vapor deposition (CVD), and high-energy beam surface treatment have high processing costs and expensive equipment. However, carburizing and nitriding methods need to be carried out at high temperature ...
