Abstract

The invention provides a cleaning method for a fine-texture metal surface for electric discharge machining. The cleaning method comprises the following steps of: firstly immersing metal for fine electric discharge machining in kerosene, cleaning the metal for 10-20min through ultrasonic oscillation, taking out the metal, putting the metal in acetone solution for continuous ultrasonic cleaning for 5-15min, then putting the metal in deionized water for ultrasonic cleaning for 5-15min, taking out the metal, blow-drying the metal, placing the metal in a plasma cleaner, cleaning the metal for 5-15min by using plasma under the power of 18W, then soaking the metal for 1-5min in hydrochloric acid water solution with concentration being 1-2mol / L, finally rinsing the metal by using deionized water, taking out the metal and blow-drying the metal to obtain the glossy wet fine-texture metal surface.

Description

technical field [0001] The invention relates to a cleaning method for electric discharge machining micro-textured metal surface. Background technique [0002] Metal surface microtexture manufacturing is to manufacture structures with various shapes, different dimensions, different scales and different functions on the metal surface. It is an emerging multidisciplinary interdisciplinary research developed in the past 30 years. [0003] Textured metal surfaces have become a research hotspot in the field of tribology because of their advantages in storing lubricants, containing wear debris, and providing surface lubrication bearing capacity. At the same time, the textured surface also has many functions such as adhesion and desorption, enhanced heat transfer, drag reduction, noise reduction and self-cleaning, video stealth, structural color, water collection, etc. research hotspots. The surface texture processing technology has been continuously developed and enriched. At pr...
