Abstract

The invention discloses a method for preparing an anti-corrosion pure Ti film through DC magnetron sputtering. The method comprises the steps such as substrate surface processing, placement of a coating chamber on a substrate, substrate surface cleaning with reverse sedimentation, sputtering coating and production of a finished product after removal of a coated substrate. The method has the beneficial effects that rational technologies of surface processing, tooling fixation and sputtering coating can be adopted aiming at products such as valves and reaction kettles; the pure Ti film can be loaded on surfaces of the products, so the products can satisfy requirements for quality and corrosion prevention; technological processes are simple and efficient; courses are controllable; no environmental pollution is generated; and industrial production can be realized easily.

Description

technical field [0001] The invention relates to the technical field of preparation of functional thin film materials, in particular to a method for preparing corrosion-resistant pure titanium thin films by DC magnetron sputtering. Background technique [0002] Titanium and titanium alloys have excellent properties such as good corrosion resistance and high specific strength, and are especially immune to erosion by salt, acid, alkali or seawater and marine atmospheric environments, and are high-quality corrosion-resistant materials. With the rapid development of shipbuilding, marine engineering, and chemical industries, products with special performance requirements such as valves and reactors are gradually being replaced by titanium and titanium alloys with better corrosion resistance from the original steel materials and stainless steel. However, titanium and titanium alloys are difficult-to-process materials and are expensive. The present invention provides a method for pr...
