钛涂层厚度和喷涂频次对植入物假体疲劳性能的影响研究OACSTPCD
Effects of Ti coating thickness and spraying frequency on fatigue strength of implants
目的:研究钛涂层厚度和喷涂频次对植入物假体疲劳强度的影响,为假体涂层厚度确定和喷涂工艺管控提供一定的理论依据.方法:根据ASTM F1160-14要求,对300和600 μm厚钛涂层的Ti-6Al-4V合金基体试样施加垂直向下的载荷,直到载荷下降时停止测试,记录各试样在测试过程中的最大极限载荷,并推算弯曲应力.之后对2种试样以正弦波形施加107次垂直向下的循环载荷,得到抗弯曲疲劳的最大弯曲应力值,以确定不同钛涂层厚度对基体疲劳性能的影响.根据IS…查看全部>>
Objective To explore the effects of Ti coating thickness and spraying frequency on the fatigue strenght of implants,so as to provide theoretical basis for determining coating thickness and controlling spraying process.Methods A vertically downward load was applied to 300-and 600-μm-thick titanium-coated Ti-6Al-4V alloy substrate specimens until the test was stopped at the drop of the load according to the requirements of ASTM F1 160-14,with the maximum ultim…查看全部>>
