Effect of Rare Earth Element Cerium on Mechanical Properties and Morphology of TiN Coating Prepared by Arc Ion Plating

TiN coatings were deposited on polished substrates of W18Cr4V high speed steel by means of vacuum arc ion plating. The effect of cerium on adhesion between TiN coating and substrate was studied. The microstructures and composition of TiN coatings were also investigated by means of scanning electron microscope (SEM), Auger electron spectroscopy (AES), and X-ray diffraction (XRD) technique. It was found that cerium is an effective modifying agent and the addition of suitable amount of cerium to TiN coatings can produce relatively excellent properties such as micro-hardness, wear resistance, oxidation resistance and porosity. The experimental results show that the added cerium in TiN coatings makesa contribution to form the preferred direction along with a (111 ) or (222) close packed face, which may be one of the reasons that improves some properties mentioned above.

用乙酰甘油酯提高结晶率

为降低晶间蜜粘度和消泡,曾单用或合用α-甲基甙脂肪酸酯,山梨糖醇酐脂肪酸酯等表面活性剂,其效果随糖浆纯度波动,对低、高纯度糖浆效果不理想。试验发现加一种或一种以上乙酰甘油酯效果显著。糖膏纯度80％以上,宜用单乙酰二脂肪酸甘油酯及二乙酰单脂肪酸甘油酯;纯度50％以下,宜用单乙酰单脂肪酸甘油酯及单乙酰二脂肪酸甘油酯;纯度50～80％,宜同时添加两种乙酰甘油酯。乙酰甘油酯所用脂肪酸,可以任选破原子数8～22的饱和脂肪酸或碳原子数8～18的不
