摘要

本文采用等离子体热喷涂和氧乙炔火焰技术，将两种不同的生物活性玻璃粉分别添加0和2%摩尔氧化镁，制备了生物活性玻璃涂层。金属基体为Ti6Al4V合金和AISI 316L钢。在模拟生物流体(SBF)存在的情况下，采用球盘法对涂层的摩擦学行为进行了评估，结果与涂层的力学行为相关联，获得了硬度(4.84 ~ 5.18 GPa)和断裂韧性(5.25 ~ 6.62 mpa . m2 /2)的值。结果表明，断裂韧性对涂层磨损性能的影响略高于硬度。

Wear Behavior of Bioactive Glass Coatings Deposited by Thermal Spraying

In this work, bioactive glass coatings were fabricated by plasma thermal spraying and oxyacetylene flame techniques from 2 different bioactive glass powders with 0 and 2% molar MgO. The metal substrates used were Ti6Al4V alloy and AISI 316L steel. The tribological behavior of the coatings was evaluated by the ball-on-disc method in the presence of simulated biological fluid (SBF), and the results were correlated with their mechanical behavior, obtaining values of hardness (between 4.84 and 5.18 GPa) and fracture toughness (between 5.25 and 6.62 MPa.m1/2). The results show that fracture toughness has a slightly higher effect than hardness on the wear behavior of the coatings under study.
