    • 专利摘要:
    A pulverulent material is obtained composed of particles or agglomerates which do not segregate when the material is projected at high temperature onto a substrate by subjecting a mixture of two or more materials in powder form to heat treatment at a sufficient temperature and for a sufficient time to produce chemical reaction between the materials and temporary softening of the materials. A pulverulent material is thereby formed consisting of spheroidal particles or spheroidal agglomerates. The specification describes the production of pulverulent material consisting of: a cermet of Al2O3, Ni, and Al; a matrix of Ni-Cr alloy containing inclusions of niobium carbonitride; an Al2O3-Cu cermet nucleus surrounded by a surface layer of Al2O3; and TiO2-Al2O3-SiO2.

    11z () the breeder removes powdered metallurgy, in particular, to obtain a powder material, intended primarily for applying gas-thermal coatings.
    The purpose of the invention is to improve the quality of the coatings obtained by spraying a powder material.
    The initial mixture of powders and phenol binder is granulated, the granules are heated to remove the phenol binder, and then heat treated. For this, the granules are passed through a plasma jet, and the temperature of the granules when passing through the specified jet is 1200-2000 ° (. Due to the fact that chemically the composition of the gas plasma can be corrected in accordance with the requirements for the final product, during heat treatment interaction not only between the components, but also their reaction with the gaseous medium. In accordance with this, granules of complex chemical composition with high strength and wear resistance are obtained. The processing below does not ensure the completion of the chemical interaction processes between the gaseous medium and the components of the granules, and heating to temperatures of 2000 ° C is accompanied by the destruction of the granules. In both the first and second cases, the first sheets obtained from such powder materials are characterized by low quality (poor adhesion to the surface of the coated product).
    The chemical composition of the granules and the mode of their heat treatment (according to the optimal variant) are given in that bl. one.
    The properties of thermally sprayed coatings (oxy-acetylene torch, distance from nozzle to substrate 200 mm, powder feed rate 5 g / h) are given in Table. 2-6 (in tab. / - for the chemical composition of 1 granules in table. 1, in table. 3 - for composition 2, table 1, in table. 4 - for composition 3, table 1, in table. 5 - for composition 4 Table 1 and Table 6 for Formulation 5 Table 1).
