The contacting surfaces subjected to progressive loss of material known as 'wear,' which is unavoidable between contacting surfaces. Similar kind of phenomenon observed in the human body in various joints where sliding/rolling contact takes place in contacting parts, leading to loss of material. This is a serious issue related to replaced joint or artificial joint.
Out of the various material combinations proposed for artificial joint or joint replacement SiN against AlO is one of in ceramic on ceramic category. Minimizing the wear loss of SiN is a prime requirement to avoid aseptic loosening of artificial joint and extending life of joint.
In this paper, an attempt has been made to investigate the wear loss behavior of SiN-hBN composite and evaluate the effect of hBN addition in SiN to minimize the wear loss. DoE-Taguchi technique is used to plan and analyze experiments.
Analysis of experimental results proposes 15 N load and 8 % of hBN addition in SiN is optimum to minimize wear loss against alumina.
接触表面会出现材料逐渐损失的现象，即“磨损”，这在接触表面之间是不可避免的。在人体的各种关节中也观察到类似现象，在这些关节的接触部位会发生滑动/滚动接触，从而导致材料损失。这是与置换关节或人工关节相关的一个严重问题。
在为人工关节或关节置换提出的各种材料组合中，氮化硅对氧化铝属于陶瓷对陶瓷类别。将氮化硅的磨损损失降至最低是避免人工关节无菌性松动和延长关节寿命的首要要求。
在本文中，尝试研究氮化硅-六方氮化硼复合材料的磨损损失行为，并评估在氮化硅中添加六方氮化硼对最小化磨损损失的影响。采用实验设计-田口方法来规划和分析实验。
实验结果分析表明，15牛的载荷以及在氮化硅中添加8%的六方氮化硼是使与氧化铝接触时磨损损失最小化的最佳条件。
