Problems solved by technology

In addition, the development experience of traditional alloys tells us that although the properties of alloys can be improved by adding a small amount of specific alloying elements, too many types of alloying elements will lead to the appearance of many compounds, especially brittle intermetallic compounds, which will lead to the deterioration of alloy properties. Such as becoming brittle, in addition, it also brings great difficulties to the structure and composition analysis of materials

Embodiment 1

[0024] The specific preparation process of the preparation method of the plasma cladding high-entropy alloy coating mentioned in the present invention is as follows:

[0025] a) Substrate pretreatment, firstly, cut the low-carbon steel plate into a plate with a thickness of 10mm, a width of 100mm, and a length of 2000mm; then, use a milling machine to cut the surface of the carbon steel plate to remove the oxide layer until the metallic luster is exposed; Then, degrease and clean the carbon steel plate. The main component of the degreasing agent is potassium hydroxide, and an organic complexing agent is used as a cleaning aid. The temperature is controlled at about 25°C during cleaning. Surface and dry, set aside.

Abstract

The invention relates to a preparation method of a plasma cladding high-entropy alloy coating layer, and belongs to the technical field of a coating layer. The method comprises the following steps: pretreating a base material; selecting metal powder according to the mass percent:5% to 35% of Cr, 5% to 35% of Co, 5% to 35% of Fe, 5% to 35% of Mn, 5% to 35% of Ni and 5% to 35% of Cu; adding a slagging constituent, wherein the slagging constituent comprises the following components by weight percent: 50% to 100% of rutile, 0% to 25% of fluorite and 0% to 25.% of mica; evenly mixing the metal powder and the slagging constituent; and preparing the coating layer by using plasma spray welding equipment. The method is reasonable in process arrangement, simple to implement and moderate in cost, thereby being suitable for popularization. The prepared coating layer is strongly bonded with the base material, and is excellent in surface quality, stable in comprehensive mechanic performance and good in durability.

Description

technical field [0001] The invention relates to the field of multi-principal high-entropy alloy materials, in particular to a method for preparing a plasma cladding high-entropy alloy coating, which belongs to the technical field of coatings. Background technique [0002] The design of traditional alloys does not deviate from the method of using one or two elements as the main components, and then adding other elements to improve the structure and properties of the alloy. Human beings have prepared different alloys based on this concept, such as stainless steel, aluminum alloy, Ti-Al binary intermetallic compound, and amorphous alloys that have emerged in recent years. In addition, the development experience of traditional alloys tells us that although the properties of alloys can be improved by adding a small amount of specific alloying elements, too many types of alloying elements will lead to the appearance of many compounds, especially brittle intermetallic compounds, wh...
