Title: Flame-sprayed alumina on stainless steel for possible prosthetic application. Author: Baldwin CM, Mackenzie JD. Journal: J Biomed Mater Res; 1976 May; 10(3):445-53. PubMed ID: 1270460. Abstract: 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.[Abstract] [Full Text] [Related] [New Search]
