Effect of Al2O3 content on the high-temperature oxidation behaviour of CoCrAlYTa coatings produced by laser-induction hybrid cladding
Source abstract
Abstract
The microstructure and isothermal oxidation behaviour of CoCrAlYTa coatings containing different Al 2O 3 contents produced by laser-induced hybrid cladding (LIHC) were investigated. The results showed that the addition of Al 2O 3 particles to the CoCrAlYTa coatings reduced the critical concentration of Al due to the increased diffusion coefficient of Al, which promoted the formation of continuous and complete Al 2O 3 scales. However, the growth of tantalum oxide in the CoCrAlYTa coating resulted in cracking of the surrounding oxide scales. Interestingly, a CoCrAlYTa coating made of the optimal content of 2 wt% Al 2O 3 formed an oxide scale with good compactness after high-temperature oxidation.
