摘要：鉆井泵的十字頭易磨損失效，目前主要采用表面改性技術(shù)來(lái)提高其耐磨性能。針對(duì)巴氏合金澆注、電弧噴涂、等離子噴焊和高速激光熔覆4種表面改性技術(shù)，從磨損機(jī)理、涂層結(jié)合強(qiáng)度、涂層材料及質(zhì)量等技術(shù)角度對(duì)其進(jìn)行對(duì)比分析。分析結(jié)果可為鉆井泵十字頭的表面耐磨技術(shù)評(píng)價(jià)體系建立及其應(yīng)用提供參考。

Abstract：The crosshead of drilling pump is prone to wearing failure. The surface modification technology is mainly used to improve its wearing resistance. Four surface modification technologies， including babbitt alloy pouring， arc spraying， plasma spray welding and high-speed laser cladding were compared and analyzed from the technical perspectives of wear mechanism， coating bonding strength， coating material and quality. It provides a reference for the establishment and application of the evaluation system of the surface wear resistance technology of the drilling pump crosshead.

Key words：drilling pump; crosshead; wear resistance; surface modification; technique

鉆井泵的十字頭工作時(shí)，在金屬導(dǎo)板內(nèi)做高速直線往復(fù)運(yùn)動(dòng)（如圖1所示），在服役過(guò)程中不可避免要與導(dǎo)板發(fā)生相對(duì)摩擦，造成表面磨損，從而影響其使用壽命［1］。（剩余5585字）
