摘要: 目的 探讨不同喷砂参数对医用四级纯钛表面粗糙度的影响,为优化纯钛大颗粒喷砂酸蚀表面性能提供参考。方法 采用氧化铝颗粒利用正交实验设计,进行不同参数条件下的医用四级纯钛表面喷砂处理,通过正交实验极差和方差分析,分析喷砂的粒度、压强、距离及时间对医用四级纯钛表面平均粗糙度(roughness average,Ra)的影响。结果 本实验因素水平范围内可获得Ra值1.083~2.494 μm粗糙度表面。其中最小表面粗糙度(A组)参数为喷砂材粒度100目、压强0.2 MPa、喷砂距离50 mm、时间60 s,最大表面粗糙度(B组)参数为喷砂材粒度60目、压强0.4 MPa、喷砂距离100 mm、时间15 s。结论 在本实验因素水平范围内Ra值随喷砂粒度和时间的增大而减小,随喷砂压强和距离的增大而增大。

Abstract: Objective This study investigates the effect of different sandblasting parameters on the surface roughness of medical-grade Grade 4 pure titanium, aiming to provide reference data for optimizing SLA(sandblasted, large-grit, acid-etched) surface characteristics. Methods Alumina particles were used in an orthogonal experimental design to analyze the effects of particle size, pressure, distance, and time on the surface roughness average (Ra) of Grade 4 pure titanium. Range analysis and variance analysis were performed to evaluate the impact of each parameter. Results The surface roughness with Ra value of 1.083~2.494 μm can be obtained within the range of factor levels in this experiment. The lowest surface roughness (Group A) was achieved with 100-mesh particles, 0.2 MPa pressure, a distance of 50 mm, and a duration of 60 seconds. The highest surface roughness (Group B) was observed with 60-mesh particles, 0.4 MPa pressure, a distance of 100 mm, and a duration of 15 seconds. Conclusion Within the range of parameter levels examined in this study, surface roughness decreased with increasing particles size and blasting time, while it increased with higher pressure and longer blasting distance.
