采用机械加工技术在硼磷合金铸铁缸套表面制备了12种微坑型织构，并采用机械球磨的方式填充3种固体润滑剂，研究了其在200 r/min、150℃、60 M Pa、油润滑的工况条件下的减摩与抗黏着磨损性能。结果表明：微坑直径为0．4mm、微坑间距离为3倍直径、微坑深度为0．5mm的缸套试样的摩擦性能和抗黏着磨损性能最优，相比原始缸套试样，摩擦系数下降了33．3％，抗黏着磨损时间延长了73％，填充二硫化钼的缸套试样减摩及抗黏着磨损效果最好。

On the surface of boron phosphorus alloy cast iron cylinder liner 12 micro-pit knitted structures were prepared by the mechanical processing technology and were stuffed with 3 solid lubricants .Under the lubrication conditions of 150 ℃ and 60 MPa lube oil in 200 r/min ,the anti-friction and anti-adhesive wear properties were studied .The results show that the cylin-der-liner specimen with micro-pit of 0 .4 mm in diameter ,0 .5 mm in depth and spacing of 3 times diameter has optimal friction and anti-adhesive property .Compared with the original cylinder-liner specimen ,the friction coefficient of stuffing specimen de-creases by 33 .3% and its anti-adhesive wear period prolongs by 73% .It is also found that the cylinder-liner specimen stuffed with MoS2 has the best anti-friction and anti-adhesive wear property .
