Tool capable of inhibiting deformation of spraying test piece

Abstract

The invention relates to a tool capable of inhibiting deformation of a spraying test piece. The tool comprises a supporting piece used for supporting the test piece, and a positioning piece installed on the supporting piece. The positioning piece comprises at least two end positioning pieces which are located on the two opposite sides of the supporting piece respectively and used for pressing the two ends of the test piece, side face positioning pieces which are located between the two end positioning pieces and used for clamping the two sides of the test piece, and a plate face positioning piece which is located between the two end positioning pieces and used for abutting against the plate face of the test piece. The positioning mechanisms are arranged at the two ends, the two sides and the bottom of the test piece to position the test piece in all directions, so that bending deformation of the test piece under various conditions in the cold gas spraying process is effectively inhibited, and the technical requirement for verifying the additive manufacturing quality through the test piece is met.

Description

technical field [0001] The invention relates to the field of spraying, in particular to a tool capable of suppressing the deformation of a spraying test piece. Background technique [0002] At present, the metal additive remanufacturing process is a process of depositing metal on the surface of the substrate to form various types of coatings. With the development of science and technology, traditional electroplating and other high-pollution and low-strength surface treatment processes are gradually being replaced by metal remanufacturing. The latter has the main characteristics of high coating bonding strength, low porosity, wear resistance, high temperature resistance, and salt and alkali corrosion resistance. It has been involved in metallurgy, pharmaceuticals, petroleum, aviation and other fields. As a new surface engineering and processing technology in the 21st century, cold gas dynamic spraying has been applied to the actual production work of the aviation industry bec...
