Abstract

The invention discloses a water-base lubricant for titanium alloy machining and a preparation method thereof. The water-base lubricant comprises the following substances: titanium oxide nano-particles, dispersing agent, de-foaming agent, auxiliaries and the balance of deionized water, wherein the concentration of titanium oxide nano-particles is within 15-30g / L; the concentration of dispersing agent is within 10-25g / L; the concentration of de-foaming agent is within 2-10g / L. The above components indicate that the water-base lubricant for titanium alloy machining and the preparation method thereof disclosed by the invention have the advantages of convenience in taking raw materials, simple preparation process and method, and easiness in laboratory and industrial production. Water is servedas a main body of the water-base lubricant for titanium alloy machining, so that the water-base lubricant has an excellent cooling effect, can be easily cleaned, is pollution-free to environment, is harmless to human health and belongs to an environment-friendly lubricant.

Description

technical field [0001] The invention relates to the technical field of a lubricant used for machining titanium alloys, in particular to a water-based lubricant used for machining titanium alloys and a preparation method thereof. Background technique [0002] Titanium alloys have high specific strength and excellent corrosion resistance and are widely used in medical, automotive, aerospace, marine and other industrial fields. However, titanium alloys have extremely poor friction and wear properties. Under dry sliding conditions, direct metal-to-metal contact is likely to cause severe wear and failure on the surface of titanium alloy components. Applying traditional lubricants such as lubricating oil and grease on the surface of titanium alloy components is a cheap, fast and effective treatment method. Traditional lubricants are generally prepared on the basis of mineral oil, animal and vegetable oil or their mixtures, adding various additives. Because this type of lubricant...
