▎ 摘　　要

NOVELTY - Titanium carbide/graphene/chromium-molybdenum-based amorphous alloy gradient coating comprises a first coating layer, a second coating layer and a third coating layer. The first coating layer, the second coating layer and the third coating layer are orderly arranged close to the base body and far away from the base body. The base body is a boiler tail heating surface. The raw material of each coating comprises 3-5 wt.% titanium carbide powder, 3-5 wt.% modified graphene powder and 90-94 wt.% chromium-molybdenum-based amorphous alloy powder. The second coating layer comprises 7-9 wt.% titanium carbide powder, 7-9 wt.% modified graphene powder and 82-86 wt.% chromium-molybdenum-based amorphous alloy powder. The third coating layer comprises 11-13 wt.% titanium carbide powder, 11-13 wt.% modified graphene powder and 74-78 wt.% chromium-molybdenum-based amorphous alloy powder. USE - Titanium carbide/graphene/chromium-molybdenum-based amorphous alloy gradient coating is used for boiler. ADVANTAGE - The titanium carbide/graphene/chromium-molybdenum-based amorphous alloy gradient coating effectively reduces stress concentration caused by too large difference between the coating and the matrix thermal expansion coefficient, improves the bonding strength of the coating layer and the boiler tail heating surface substrate, and reduces the risk of coating cracking and peeling. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the coating.
