Abstract

The invention discloses a water-based cutting fluid for molybdenum alloy processing. The water-based cutting fluid is composed of base oil, a rust inhibitor, a synthetic lubricant, a surfactant, a novel surfactant, a metal corrosion inhibitor and water. The water-based cutting fluid for molybdenum alloy processing has favorable molybdenum corrosion resistance and excellent pH value maintenance property for the use solution.

Description

technical field [0001] The invention relates to a water-based cutting fluid for molybdenum alloy processing. Background technique [0002] Molybdenum alloy is a non-ferrous alloy composed of molybdenum as the matrix and adding other elements. Because of its good thermal conductivity, electrical conductivity and low expansion coefficient, molybdenum alloy has the characteristics of high strength and high temperature resistance at high temperature (1100-1650 ℃), and has been widely used in civil and military applications. Alloys of molybdenum, nickel, and chromium are used to manufacture metal components of aircraft, corrosion-resistant parts on locomotives and automobiles, and alloys of molybdenum, tungsten, chromium, and vanadium are used to manufacture alloy components of warships, tanks, guns, rockets, and satellites. parts. [0003] In the finishing process of molybdenum alloys, due to the high strength and hardness of molybdenum alloys, the cutting and grinding heat ge...
