Abstract

The present invention discloses machining process of forming nanometer layer on the surface of metal material. The machining process includes chucking the nanometer machining head of the ultrasonic metal surface nanometer processing apparatus onto the tool carrier of lathe; and turning on the power and the control switches in the ultrasonic generator and the executor and regulating the machining parameter to machine the metal material. The said parameters includes the main lathe shaft rotation speed of 50-1200 rpm, the feeding amount of the nanometer machining head in 0.02-0.5 mm / r, the linear machining rate of 1-600 mm / min, the reciprocating time number of 1-10 and the output amplitude of the ultrasonic surface machining head in 5-50 microns. The present invention has simple machining condition, high machining quality, less pollution and other advantages.

Description

technical field [0001] The invention relates to designing a method and equipment for surface treatment of metal materials, more specifically, a method and equipment for processing nano-layers on the surface of metal materials. Background technique [0002] Mechanical parts and structures are widely used in important fields such as ships, pressure vessels, vehicles, bridges, ocean engineering, construction machinery, aerospace, electric power, metallurgy, etc. How to ensure their safe operation during service is a major issue in the development of the national economy , especially in today's premature failure of mechanical structures and frequent safety accidents. There are many physical mechanisms that cause failure of mechanical structural equipment, such as fatigue, creep, corrosion, brittle fracture, wear, etc. Among them, fatigue damage, wear and corrosion problems are more common. Therefore, it is of great economic and practical importance to study new methods of surfa...
