Abstract:
A process for applying and bonding a solid lubricant on a substrate whose surface has depressions and pores. The process comprises depositing fine solid lubricant particles on the surface of a substrate to be lubricated in excess of a quantity sufficient to fill essentially all depressions and pores on the substrate surface, and thereafter burnishing the substrate to distribute and bond the lubricant particles on the substrate. Such burnishing of the substrate can be accomplished during its moving contact with another substrate during intended use. Maintenance of lubricity can be accomplished by depositing additional lubricant particles on the substrate and thereafter burnishing, and can be performed while the substrate is in moving contact with another substrate whereby this moving contact performs the burnishing operation.
Abstract:
Water-based metal-containinig organic phosphate compositions which are useful as corrosion-inhibiting coating compositions, metal working lubricants and drilling fluids for well-drilling operations. These compositions comprise: (A) water or an aqueous drilling mud; (B) an overbased non-Newtonian colloidal disperse system comprising (B) (1) solid metal-containing colloidal particles predispersed in (B) (2) a dispersing medium of at least one inert organic liquid and (B) (3) at least one member selected from the class consisting of organic compounds which are substantially soluble in said dispersing medium, the molecules of said organic compound being characterized by polar substituents and hydrophobic portions; and (C) a metal-containing organic phosphate complex derived from the reaction of (C) (1) at least one polyvalent metal salt of an acid phosphate ester, said acid phosphate ester being derived from the reaction of phosphorus pentoxide or phosphoric acid with a mixture of at least one monohydric alcohol and at least one polyhydric alcohol, with (C) (2) at least one organic epoxide. These compositions preferably include an effective amount of (D) an alkali or an alkaline earth metal salt of an organic acid, (E) a carboxylic acid and (F) an N-(hydroxyl-substituted hydrocarbyl) amine to enhance the dispersion of components (B) and (C) with said water or drilling mud (A).
Abstract:
Sulfur-based additives, which are essentially labile-sulfur free, are employed in lubricants and functional fluids to substantially eliminate the problem of metal corrosivity and elastomer degradation generally exhibited by sulfur-based additives.
Abstract in simplified Chinese:水系冷却剂系掺合下述物质而成:选自于碳酸盐、碳酸氢盐、倍半碳酸盐、磷酸盐、硼酸盐、钼酸盐、及钨酸盐之1种以上的无机酸盐;以及金属防腐蚀剂。本发明的水系冷却剂系具有高冷却性能,且冷却对象的金属材料不易发生腐蚀。所以,本发明的水系冷却剂颇适用为热处理油或切削油。
Abstract in simplified Chinese:一具有优良的冷却性以及润滑性、且对环境不曾造成坏影响的水溶性切削液。其含有碳酸氢离子、溴化物离子、碳酸离子以及因应必要之氟化物离子,pH调整为7.0~11.5之水溶液能直接作为切削液使用,或于其中混合防锈剂等添加物而调制出水溶性切削液,可作为以往的切削油之代用品使用。
Abstract in simplified Chinese:采不锈钢线镀以镍(Ni)达到不小于lμm至不大于5μm的厚度。然后将一片无机盐类涂层薄膜(主要系由硫酸钾和硼砂(硼酸盐)之至少一种所组成且不含氟(F)或氯(cl))淀积在作为基体之镍(Ni)镀层之上。然后将(不锈)钢线拉伸至减小面积不少于60%来调整其表面粗度至0.80至12.5μmRZ的范围,宜为自1.O至10.0μmRZ。
