| 中文摘要: |
| 采用热化学反应热喷涂技术,向骨料中加入坡缕石制得喷涂喂料粉末,在Q235钢表面制备含坡缕石的三元硼化物陶瓷涂层,观察了涂层的显微组织,测试了涂层的耐磨性能,分析了坡缕石对三元硼化物陶瓷涂层显微组织和耐磨性的影响。结果表明:坡缕石的添加,使得涂层变得致密且具有一定减摩效果;坡缕石的添加量占骨料总质量的2%时,所得三元硼化物陶瓷涂层的耐磨性比未加坡缕石时平均提高4倍。 |
| 英文摘要: |
| Spraying feeding powder was produced through adding palygorskite. Ternary boride ceramic coating containing palygorskite was prepared by thermochemical reactive thermal spaying on Q235 steel substrate. The micro-structure of coating was observed, and the wear-resistance performance of coating was tested. The influence of palygorskite on microstructure and wear-resistance of ternary boride ceramic coating was analyzed. The results show that coating become compact and anti-friction because of adding palygorskite. When the adding dosage of palygorskite is 2% of the total aggregate quality, the abrasion resistance of coating has increased 4 times averagely than the coating without paly-gorskite |
