Architectured Multi-Metallic Structures Prepared by Cold Dynamic Spray Deposition

Abstract

The architectured metallic materials are a class of composite materials that combines two or more metals/alloys with a specific spatial ordering (architecture). The main goal behind the preparation of such materials is to obtain properties that are not achievable by a single material. The internal architecture thus creates an extra degree of freedom in materials design. Based on theoretical considerations three aluminum alloy structures containing square, triangle and sinusoidal iron beam patterns have been prepared by a cold spray deposition technique. Strength properties difference and good bonding of the reinforcing Fe structure to the Al matrix has been found to be important for effective improvement of final properties. Incorporating about 30 vol. % structured iron beams into the Al matrix resulted in a macroscopic performance of the architectured multimaterial similar to Ti alloys.

Processing of Bimetallic Inconel 625-16Mo3 Steel Tube via Supercritical Bend: Study of the Mechanical Properties and Structure

“…Therefore, changes in the layers after bending also significantly impact corrosion resistance. The next solution for applying the protective layer is cold dynamic spray deposition [34], which will be our objective in the next study.…”

Possibilities of Using the Duplex System Plasma Nitriding + CrN Coating for Special Components

“…Good properties of chrome coatings have been achieved using the HVAF (High Velocity Air-Fuel) method [20][21][22][23][24], which can also be used as an alternative to hard chrome plating. Currently, CS (Cold Spray) technology is coming to the fore, which can be used to replace hard chrome with alternative surface processes or to produce a hard chrome layer without the use of Cr6 [25][26][27]. Currently, the possibility of replacing exposed steel components with composite materials is increasing [28][29][30].…”
