Investigation on mechanical property of annealed copper particles and cold sprayed copper coating by a micro-indentation testing

Characteristics and performance of hard Ni60 alloy coating produced with supersonic laser deposition technique

“…In the CS process the particles are accelerated by a high-velocity jet stream that is generated via the expansion of pressurized, preheated nitrogen or air in a vonverging-diverging nozzle to exceed critical plastic deformation velocity [17,19]. Currently, cold spray is mainly employed to deposit relatively soft, heat sensitive and oxidation sensitive materials such as Al, Cu, Ti, 316, Ni-based 25 alloy, soft matrix composite powder such as WC/Co, diamond/Ni, and amorphous material [20][21][22][23][24][25][26][27], but it is difficult to deposit high hardness particles such as Stellite 6, Ni60, diamond, WC, and metal-ceramic materials, or prohibitively expensive to process by cold spray [28].…”

Characterisation studies of linear friction welded titanium joints

“…Fig. 3 is the schematic of the cross-section of one indentation [34]. The material undergoes both elastic and plastic deformation during the indenter plunging into the material.…”

Implementation of the new minimum resultant error approach to extract elastic-plastic properties of titanium nitride thin film by nanoindentation, finite element analysis, and modified dimensional analysis

“…Therefore, the friction between the indenter and the sample surfaces has been mulled over in some studies. 42,43 For metallic materials, friction coefficients from 0.1 44 to 0.6 4 are considered in some studies. Investigation results have revealed that the maximum difference up to 0.4% is occurred in most apparent cases.…”
