Abstract
The invention discloses a method for preparing mechanical coating powder through slurry coating, heating and curing, and belongs to the technical field of aero-engines and gas turbines. The method comprises the following steps that (1), abradable component powder, skeleton component powder and a binder are configured into slurry and uniformly stirred; (2) a three-stage mechanical coating poweringprocess which is capable of simultaneously heating and stirring of "slurry wrapping + heating and curing" on uniformly dispersed slurry is carried out, the first stage is high-temperature rapid turbotype stirring to realize slurry wrapping of materials; the second section is medium-temperature medium-speed frame type stirring, so that heating and curing of an organic adhesive film are realized; and the third section is low-temperature low-speed paddle type stirring, so that flexible scattering of solid particle agglomerates is realized; and (3), screening the scattered powder is carried out to obtain final finished powder. Compared with the prior art, by the adoption of the method for preparing the mechanical coating powder through slurry coating, heating and curing, the powder yield canbe increased by 40% or above, and the powder preparation time can be shortened by 20% or above.
