Research and development of technology for obtaining small-scale GTE parts from ceramic composite materials by 3D printing

Abstract

In modern production, direct laser deposition technologies are used to shorten the time of production of a new product at the design and manufacturing stages. The development of technology follows the path of introducing new powder materials and determining rational technological regimes for the formation of a surface layer of specified quality. This work is about study of samples from a cermet composite material (CCM) by direct laser deposition. Technological parameters for defect-free build-up of full-size small-sized parts of gas turbine engines (GTE) are determined. Structures were studied and tests were conducted to determine the mechanical properties of deposited laboratory samples. The technology of full-size small GTE parts manufacturing has been worked out.
