硫化作用

Oxygen plays critical roles in lubrication mechanism. Oxygen affects the lubrication mechanism of additives all along, whether in sulfurized vegetable oil fatty acids containing active element or not in hydroxy vegetable oil fatty acids with pure carbon, hydrogen and oxygen not containing active element.

氧元素在润滑机理中有着关键作用，无论在含活性元素的硫化植物油脂肪酸，还是在不含活性元素的纯碳、氢和氧的羟基植物油脂肪酸中，氧元素始终影响着添加剂的润滑性。

A four-ball tester was used to evaluate the load carrying and antiwear properties of bismuth dibutyldithiocarbamate,bis-dibutyldithiocarbamates(V7723),sulfurized isobutylene,molybdenum ester non sulfur and phosphorus in a mineral oil respectively and their synergistic effects.

利用四球试验机评价了二丁基二硫代氨基甲酸铋与二丁基二硫代氨基甲酸酯(V7723)、硫化异丁烯和非硫磷钼酸酯添加剂的极压和抗磨性能，以及它们之间的极压和抗磨协同作用。

A four ball tester was used to evaluate the antiwear and extreme pressure properties of antimony dialkyldithiophosphate with friction reducer containing phosphorus, chlorinated paraffin(T301) and sulfurized isobutylene (T321), and their synergistic effects.

利用四球试验机评价了二烷基二硫代磷酸锑与含磷摩擦改进剂、氯化石蜡(T301)、硫化异丁烯(T321)3种添加剂的极压和抗磨性能，以及它们之间的极压和抗磨协同作用；利用市售演示仪评价了SbD-DP、T301和T321之间的协同抗擦伤能力。

In the coating, the nodular defect was observed to worsen severely the properties. For testing under oxidation condition, the nodular defect results in the internal oxidation of Al. No single Al oxide scale may be formed at 1100℃ owing to consumption of Al. Under hot corrosion, it becomes as short-path for diffusion of S through the coating, thus sulphuring the coating together with the substrate. During thermal shock testing, it may act as the source of cracking, and moreover, if cyclic stress applied, the cracks propagate toward the substrate, the thermal fatigue properties of coating will be worsened.

结果表明：在氧化条件下，缺陷导致Al的内氧化，在1100℃时，由于Al的大量内消耗，涂层表面已不能形成单一的氧化铝膜，使氧化性能下降；在热腐蚀条件下，缺陷成为硫向涂层中扩散的通道，导致涂层及基体的硫化；在冷热疲劳条件下，缺陷成为裂纹源，在交变应力作用下，裂纹向基体中扩展，降低了涂层的热疲劳性能。
