| Abstract: | Treated with laser the changes in microstructure and hardness of cylinder sleeve of oil-well pump for 45 steel were studied.A highly refined martensite microstructure having high hardness values(up to 880 HV0.1)was obtained in the surface hardened layer.With the proper selection of laser processing parameters both surface finish quality and dimensional accuracy were guaranteed to meet established specification.For over one year the experimental result in the oil-field showed that the service life of cylinder sleeve treated by laser is longer than that by conventional carburizing. |
