3D EVALUATION METHOD OF BINDING FORCE BETWEEN METAL MATERIAL AND METAL BASE LAMINATED ON METAL BASE BY CLADDING 3D PRINTING

摘要

Disclosed is a method for evaluating a bonding force between a metal material and a metal base material laminated to a metal base material by cladding 3D printing. The method of evaluating the bonding strength between a metal material and a metal base material laminated to a metal base material by 3D printing of the cladding method includes: a) forming a layered part by laminating metal powder to a certain thickness on a top surface of a base material part of a certain size by 3D printing; b) cutting the base material portion and the stacked portion into a predetermined shape, but cutting the base material portion and the portion of the stacked portion so as to have an interface portion to make a test piece; c) fixing the end portion of the test piece to the first jig for tension, and fixing the end portion on the stacked side of the test piece to the second jig for tension; d) applying a tensile load to the test piece through the first jig for tension and the second jig for tension; And e) evaluating the strength between the interfaces at the interface in the process of applying the load.
