The effects of Ti addition on the microstructure and tribological properties of in situ composite carbide WC-TiC/FeNi coating were studied using XRD, SEM, EDS, and friction and dry sliding wear tests. The results show that the composite carbide WC-TiC was successfully in situ synthesized in the coating, and with Ti addition increased by 0.1 from 0.1 to 0.4 wt.%, the in situ carbide TiC increased from 3.4 to 24.4 vol.%, while the carbide WC decreased from 32.5 to 24.2 vol.%, and the coating hardness increased from 1027 to 1196 HV_4.9. The friction and dry sliding wear tests show that for WC-TiC/FeNi composite coating, the addition of Ti can not only reduce the friction coefficient, the mass loss of both the coatings and its counterpart but also improve the friction stability, service life, and wear rate (WR). The relationship between the Ti addition and the coating wear rate fits the exponential decay equation WR = 10.6 − 0.089 \(\times\) e ^(Ti/0.098). The main wear mechanisms of in situ WC-TiC/FeNi composite carbide coating are abrasive wear, oxidative wear, and micro-plow wear.

利用XRD，SEM，EDS，摩擦和干滑磨损试验研究了添加Ti对原位复合碳化钨WC-TiC / FeNi涂层的组织和摩擦学性能的影响。结果表明，在涂层中成功地原位合成了复合碳化物WC-TiC，并且随着Ti的添加量从0.1增至0.1 wt。％，Ti增加了0.1，而原位TiC从3.4增至24.4 vol。％，而碳化钨的碳化物含量从32.5％降低到24.2％，涂层硬度从1027％升高到1196 HV _4.9。摩擦和干滑磨损试验表明，对于WC-TiC / FeNi复合涂层，添加Ti不仅可以降低摩擦系数，降低涂层及其相伴材料的质量损失，而且还可以改善摩擦稳定性，使用寿命，和磨损率（WR）。Ti添加量与涂层磨损率之间的关系符合指数衰减方程WR = 10.6 − 0.089 \（\ times \） e ^{（Ti /0.098）}。原位WC-TiC / FeNi复合碳化物涂层的主要磨损机理是磨料磨损，氧化磨损和微犁磨损。
