摘 要：Surface modification is often performed using grit or shot blasting treatment for improving the performances of biomedical implants.The effects of blasting treatments using steel slag balls and spherical shots on the surface and subsurface of titanium were studied in this paper.The treatments were conducted for 60-300 s using 2-5 mm steel slag balls and 3.18 mm spherical shots.The surface morphology,roughness,and elemental composition of titanium specimens were examined prior to and after the treatments.Irregular and rough titanium surfaces were formed after the treatment with the steel slag balls instead of the spherical shots.The former treatment also introduced some bioactive elements on the titanium surface,but the latter one yielded a harder surface layer.In conclusion,both steel slag ball and shot blasting treatment have their own specialization in modifying the surface of metallic biomaterials.Steel slag ball blasting is potential for improving the osseointegration quality of implants;but the shot blasting is more appropriate for improving the mechanical properties of temporary and load bearing implants,such as osteosynthesis plates.
