Title:
METHOD FOR PREPARING CORROSION-RESISTANT COATING OF MARINE WELL DRILLING PLATFORM
Document Type and Number:
WIPO Patent Application WO/2017/092065
Kind Code:
A1
Abstract:
Disclosed is a method for preparing a corrosion-resistant coating of a marine well drilling platform belonging to the technical field of preparing high-entropy alloy corrosion-resistant coatings. In the method, a double-feeding-port nozzle aerodynamic spraying technology is used to spray an Al-Cr-Fe-Mn-Ni five-component high-entropy alloy powder on a steel structure base body of a marine well drilling platform, and at the same time, a cathode protection metal Zn powder is added so as to obtain a coating having stable components and good corrosion resistance. The double-feeding-port nozzle aerodynamic spraying technology is an effective method for preparing an Al-Cr-Fe-Mn-Ni five-component high-entropy alloy corrosion-resistant coating, and the coating is large, dense, and highly corrosion-resistant, etc.
