METHOD AND TOOLING FOR DEPOSITION OF METAL COATING FROM VAPOUR PHASE ON PARTS FROM SUPERALLOYS Russian patent published in 2017 - IPC C23C16/458 C23C16/455 C23C16/12 F01D5/28 

FIELD: metallurgy.

SUBSTANCE: provision of a camera-forming box including a sidewall and a plate forming the bottom of the box is carried out. The granules of the metal donor of the mentioned coating and activator forming the coating metal halide are placed in the chamber to form an underlying layer of granules at the bottom of the box. A support for the parts comprising the plate supported by support columns is provided. The mentioned parts are suspended on the support plate. The supports are placed in the chamber on top of the underlying layer of granules located at the bottom of the box, so that the parts do not come into contact with the underlying layer of granules. The box is closed, the chamber is heated in the atmosphere of inerting or reducing gas to the reaction temperature of the coating metal halide with the heat-resistant alloy, using which the parts are made. Inerting or reducing gas is introduced into the closed box through the side wall of the box and discharged into the box above the underlying layer of granules. The proposed tooling comprises at least one box with at least one support for the mentioned parts in the form of a plate held in parallel with the bottom of the box by supporting columns and provided with receiving apertures for suspending the parts.

EFFECT: improving the implementation of the method by reducing the impact of the tooling on it and increasing the usable volume to accommodate additional parts inside the boxes, in particular, reducing the surface of the tooling relative to the surface of the parts, the number and weight of the equipment.
