Various methods of roughening type 316 stainless steel substrate surfaces for flame-spraying alumina (Al2O3) were investigated and tested for the best alumina-to-metal bond strength. Best strength values were obtained by means of roughening via anodic polarization pitting of the stainless steel. Subsequent in vitro testing indicated a severe loss in bond strength following exposure to aerated Ringer's solution. It is suggested that the utilization of flame-sprayed devices has potential in orthopedic prostheses, but precautions must be observed.
研究并测试了多种对316型不锈钢基体表面进行粗糙化处理的方法，以用于火焰喷涂氧化铝（Al2O3），从而获得最佳的氧化铝与金属结合强度。通过不锈钢的阳极极化点蚀进行粗糙化处理可获得最佳强度值。随后的体外测试表明，暴露于充气林格氏液后，结合强度会严重损失。建议火焰喷涂装置在矫形假体中有应用潜力，但必须注意防范措施。
