Abstract

This invention discloses a heat barrier coating method which uses electric beam physics vapor to deposited multi-holes branch ceramic layer, and it deposits a layer of cemented material and ceramic material with multi-holes and branch structure in order on the nickel radical high temperature alloy base surface. The preparation method makes the ceramic layer have lower heat conductivity coefficient by controlling evaporation deposition technique parameter of two sticks A and B which have different components. This invention improves heat barrier coating serving life greatly under high temperature condition.

Description

technical field

[0001] The invention relates to a thermal barrier coating method for depositing a porous dendrite ceramic layer by electron beam physical vapor phase, and the prepared ceramic layer of the thermal barrier coating has a porous dendrite structure. Background technique

[0002] With the development of modern high technology, especially in the high-temperature environment of gas turbine engines, the single use of existing metal materials can no longer meet the design and use requirements. Thermal barrier coating is a surface thermal protection technology developed in the 1960s. Its design idea is to use the superior high temperature resistance, corrosion resistance and low thermal conductivity of ceramic materials to combine ceramics and metals by coating. The matrix is ​​compounded to improve the high-temperature corrosion resistance of the metal hot-end parts, so that it can withstand higher operating temperatures, and has the effect of increasing the operating...
