摘要： 接触疲劳破坏是齿轮的主要失效形式之一． 在45#钢齿轮齿面电沉积Ni-P-Co合金层，可以显著提高其接触疲劳强度．同时，对合金层的表面形貌，表面粗糙度、显微硬度和疲劳点蚀坑形貌特征等进行了分析．
关键词： Ni-P-Co合金涂层;  接触疲劳强度;  抗点蚀能力;  45#钢;  齿轮传动    
Abstract: Contact fatigue failure is one of the failure type for steel gear．This paper researched the contact fatigue strength of Ni-P-Co alloy coating on surface of gears made from 45# stee1．Several studies on the alloying coating，such as surface shape，surface roughness，micro-hardness and shape characteristic of fatigue pitting hole were carried out． The experimental results were analyzed and conclusion was as follows：contact fatigue life and strength of steel gears with Ni-P-Co alloy coating and air-cooling after heat-treatm ent with temperature of 450 C are increased remarkably．
Key words: N i-P-Co alloy coating    contact-fatigue strength    pitting resistance    45# steel    gear drives
