摘要/Abstract

摘要： 研究了在水溶液中合成新型固体润滑兼油品添加剂一ＮｉＭｏＯ_２Ｓ_２及其原料（ＮＨ_４）_２ＭｏＯ_２Ｓ_２的条件，其最佳参数为ｐＨ＝４～５，温度为３０℃左右和ｐＨ＝７～９；温度为－５～０℃．还对产品的组成、结构及形貌进行了分析观察，并验证了ＮｉＭｏＯ_２Ｓ_２作为油品添加剂和固体润滑剂从２０～６００℃的减摩性能；证实硫代钼酸镍是一种宽温度范围的润滑剂．

关键词: NiMoO₂S₂, （NH₄）₂MoO₂S₂, 润滑油添加剂

Abstract: The process of chemical synthesis of a new kind of solid lubricant and oil additive--nickel oxythiomolybdate
and one of its precursor material ammonium oxythiomolybdate were studied. Their composition, structure and morphology were investigated by chemical analysis,
X-ray diffraction, electron microprobe and SEM. The results obtained show that their optimum parameters for synthesizing are: pH=4～5, T=30℃, and pH=7～9,
T=--5～0℃. NiMoO₂S₂ as a solid lubricant and an oil additive from 20℃ to 600℃ has good tribological behaviors, and can be regarded as a new kind of lubricant applied in a wide temperature range.

Key words: NiMoO₂S₂, (NH₄)2MoO₂S₂, additive
