摘要
介绍了液压支架中柱塞杆的失效因素,以及热喷涂技术的原理和工艺要求;通过电弧喷涂技术对柱塞杆进行修复,并对喷涂涂层进行硬度、结合强度、孔隙率和耐腐蚀性检测。
Introduce the failure factors of the plunger rod in hydraulic support, and the principle and process of thermal spraying ; Repair the plunger rod by the arc spraying , and test the hardness, bonding strength, porosity and corrosion resistance of the spray coating.
