Preparation method.
Background technique
MCrAlY coating is common surfacecti proteon high-temperature alloy material, and M indicates matrix element, usually Ni and Co.For
The mechanics and antioxygenic property for further increasing coating, other elements can be also added in alloy coat, are indicated with X, and then shape
At MCrAlYX multicomponent alloy material.The inoxidizability of coating can be got a promotion by optimization X element and content control, example
Such as when especially coating surface layer is rich in Hf, Si and other La series elements in coating, coating inoxidizability is substantially improved, this
It is to be easy to be initially formed oxide in coating surface rate because the affinity of these elements and oxygen in external environment is strong, these oxidations
Object can promote the formation of dense oxide aluminium film, and help to improve the resistance to flaking of oxidation film.In addition, the high temperature power of coating
It is also extremely important to learn performance.Studies have shown that existing majority MCrAlY material design has been concerned only with oxidation-resistant corrosion-resistant effect,
Often have ignored the mechanical property of coating.In fact, coating can occur mutually to expand with the element in substrate in long term high temperature environment
It dissipates, counterdiffusion be easy to cause " softening " of substrate and coating interface.This " softening " is because having lacked with invigoration effect
Caused by phase, it will cause matrix under the conditions of actual complex heat/mechanical loading and coating interface induce crackle or makes coating pair
External crack propagation loses resistance, reduces coating life.

The design of constituent element MCrAlYX ingredient；2) oxide dispersion intensifying is used；3) laminated coating structure designs.Existing multicomponent
MCrAlYX material mainly passes through the coating for changing X element and its content acquisition excellent combination property, but this method is not examined
Consider the compatibility between coating and matrix, be easy in workpiece use process because coating and basal body interface stress, material heat not
The problems such as matching, causes coat inside or interface to crack.When using dispersed oxide method, the oxide of disperse then plays anti-
" softening " effect, but this method the preparation process of powder is required it is excessively high, it is at high cost.The design of laminated coating structure is close
The coating process risen over year, i.e., using the coating of preparation multilayer heterogeneity and structure, typical scheme is in substrate and to apply
Bed boundary prepares one layer of resistance diffusion layer, for preventing substrate and the counterdiffusion of coating element, reduces the generation in interface " reduction " area；But
