大电流密度下活塞顶面的阳极氧化
ANODIC OXIDATION OF THE TOP SURFACE OF PISTONS WITH HIGH CURRENT DENSITY
摘 要
研究了一种在大脉冲电流密度下对活塞顶面阳极氧化处理的快速成膜方法,在电流密度为5.5～8 A/dm2时生成的膜厚达107 μm,远远超过同行业所研究的新工艺.同时采用新开发的纳米封闭处理使高厚度的膜层耐腐蚀性能大大提高.此法已广泛用于活塞顶面阳极氧化中,使生产效率提高了3倍左右.

Abstract
An anodic oxidation process with high current density was developed for high speed film forming on the top surface of piston.The film thickness was 107 μm as the current density was 5.5～8 A/dm2.The corrosion resistance of the film was improved greatly by a new nano sealing treatment.This process has been applied widely in anodic oxidation for pistons.The productivity was increased up to 3 times as before.
