连接工艺对多孔层植入体多孔层质量的影响和作用

Influence and effect of joining techniques on porous layer quality of porous coated anatomic

概况:一般连接工艺是低水平的,使多孔层植入体多孔层产生不少隐患。缺陷:一般连接工艺之所以产生隐患,是它们各自存在的缺陷,不能采用先进的举措予以克服等。应用:活性扩散焊是适用的连接工艺,有许多先进工序。结论:作者提出采用等直径的金属小球,配合以活性扩散焊工艺才能从根本上解决它引起的以应力遮挡为主的隐患。同时活性扩散焊工艺所用到的高性能钎料,其成分对人体无害。

INTRODUCTION：General joining techniques are at low level,which produces some potential problems in porous layer of porous coated anatomic （PCA）.LIMITATIONS：The problems in general joining techniques are caused by limitations of each technique,which could not be solved using advanced measures.APPLICATION：The activated diffusion brazing technology is an effective way.Its many advanced processes can solve those potential problems.CONCLUSION：The stress-shielding problem caused by PCA porous layer can be solved by using small metal balls in the same diameter in combination with the advanced activated diffusion brazing technology.Moreover,the high performance brazing metals by activated diffusion brazing technology is harmless for humans.
