中文摘要：以凹凸棒石粘土为主体，添加一些辅助材料，运用正交实验优化出能够有效地防止60Si2Mn弹簧钢在高温下氧化脱碳的最佳配比涂料。结果表明，该涂层在高温下能均匀地覆盖于钢基体表面，且不开裂，热处理后涂层能容易地从钢基体表面剥离，保护效果十分明显。
英文摘要：The best ratio of coating was optimized by orthogonal experiment, the optimal coating could prevent oxidation and decarburization of 60Si2Mn spring steel at high temperature effectively, the mainly composition of the coating is attapulgite, in addition to some ancillary materials. The results show that the coating lay over on the surface of steel matrix equably without cracking, and can be easily removed from the surface of steel substrate after cooling, the protective effect is obvious.
