Technical Field

[0002] Continuous CPED (cathode plasma electrolytic deposition) deposition coating is a coating preparation technology that combines the concepts of cathode plasma electrolytic deposition (CPED) and continuous production. CPED technology is a method of forming a ceramic coating on the surface of a metal or alloy by electrolytic deposition. This method usually uses active substances generated by plasma discharge to form a coating on the surface of the substrate. Currently, after the coating is generated, the coating will be tested, including tests on heat resistance, low temperature resistance, wear resistance, scratch resistance, etc. The coating scratch resistance test is to scratch the coating on the substrate with a hard object, and evaluate the hardness and scratch resistance of the coating surface by observing the length and depth of the scratches. At present, the scratch resistance of continuous CPED deposition coatings is tested at room temperature. Due to the changeable application environment of the coating, the scratch test at room temperature cannot represent its accuracy in the actual application environment. In order to solve the above problems, we propose a continuous CPED deposition coating test device. Utility Model Content
