ABSTRACT In the present paper experimental studies on thermodynamic behaviour of titanium and silicon oxides in a number of quaternary and pentanary molten slags have been made by means of H〓O/H〓 chemical equilibrium between copper melts and molten slags in alundum crucibles with the molybdenum plate as the liners.

本文采用H〓O/H〓定组成混合气体与钼衬坩埚中熔渣之间的化学平衡方法，实验研究了多个四元和五元熔渣中钛和硅氧化物的热力学行为。

The results are listed as following :㏕he best anti-erosion proportion of resin present is 25wt% in the condition of silicon carbide reinforced SMCC, while the alumina reinforced SMCC is 40wt%.(2) The better anti-erosion results was achieved with the ratio of silicone resin to acrylic resin containing hydroxy being 3: 1.㏕he composites coating tends to be more brittle when added in alundum particles. It also means that the maximum erosion peak of alundum reinforced SMCC tends to normal angle.甌he change of erosion rate of SMCC can be divided into two stages with the increment erodent velocity: the slow erosion stage of the beginning and the stable erosion stage.

首次发现：①SiC增强的复合涂料涂层，树脂含量为25wt％时，具有最佳耐冲蚀性能：Al_2O_3增强的复合涂料涂层，树脂含量为40wt％时，具有最佳耐冲蚀性能；②SiC增强的涂料，有机硅树脂与丙烯酸树脂的比例为3：1时的耐冲蚀性能好于1：1的复合涂料涂层；③Al_2O_3增强体使涂层变脆的倾向大于以SiC为增强体的涂层，即SiC增强的复合涂料涂层的最大冲蚀率出现在30°，Al_2O_3增强的复合涂料涂层的最大冲蚀率出现在75°～90°之间；④低速冲蚀磨损机理主要是弹性变形与疲劳；高速冲蚀磨损机理主要是显微切削和显微犁耕。
