In the course of evaluating various porous materials as candidates for prosthetic devices, a commercial stainless steel (316L) was found which was designed for porous filtration applications. Small bars (approximately to 3mm x 3mm x 20mm) were implanted in dog extremeties for periods of 10 to 15 weeks. The average tensile strength of the bone/(bone/metal) interface was found to be 0.975 kgf/mm2 (1380 psi) with no indication of variation with time of implantation. Scanning electron microscopy (SEM) combined with X-ray energy dispersive (XRED) analysis indicates production of calcified bone in the bone/metal composite. Inherent strength and porosity characteristic combined with biocompatbility indicate that this commercially available meterial is a viable implant candidate for attachment to the skeletal system.
在评估各种多孔材料作为假体装置候选材料的过程中，发现了一种专为多孔过滤应用设计的商用不锈钢（316L）。将小棒（约3mm×3mm×20mm）植入狗的四肢，时长为10至15周。发现骨/（骨/金属）界面的平均抗拉强度为0.975 kgf/mm2（1380 psi），且没有迹象表明其随植入时间而变化。扫描电子显微镜（SEM）与X射线能量色散（XRED）分析相结合表明，在骨/金属复合材料中产生了钙化骨。其固有的强度和孔隙率特性以及生物相容性表明，这种市售材料是附着于骨骼系统的可行植入候选材料。
