The mechanism of bonding in cold spraying is still a matter of some debate. In this work, copper has been cold sprayed onto aluminium alloy substrates, the surfaces of which had been prepared in a variety of ways. The coating-substrate bonding was assessed via a novel intermetallic growth method along with adhesive pull-off testing, and related to the substrate preparation method. The bond strength has been rationalized in terms of a modified composite strength model, with two operative bonding… 

Bonding between aluminium and copper in cold spraying: story of asymmetry

Abstract The bonding mechanism in cold spraying is still a matter of some debate, which requires further investigation. In the present work, aluminium powder was cold sprayed onto a copper substrate

Cold spray for ceramic metallisation: a review

ABSTRACT Since invented in 1980s, cold spraying (CS) has received numerous attentions recently because of its low heat input and high efficiency. Severe plastic deformation induced by high-velocity

Microstructural investigations on bonding mechanisms of cold-sprayed copper with SS316L steel

ABSTRACT The purpose of the study was to understand the adhesion mechanism between cold-sprayed copper and SS316L steel substrate. Coatings of 3-mm thickness were deposited by cold-spraying on steel

Effect of Substrate Preheating on Bonding Strength of Cold-Sprayed Mg Coatings

A poor bonding strength between the magnesium coating and substrate limits magnesium coating’s application. This paper aims at improving the bonding strength between the coating and substrate using

Influence of Annealed Aluminum Properties on Adhesion Bonding of Cold Sprayed Titanium Dioxide Coating

It is well known that cold spraying ceramic materials can be difficult because cold spraying requires plastic deformation of the feedstock particles for adhesion to the substrate. The challenge lies

Influence of Powder Plasticity on Bonding Strength of Cold-Sprayed Copper Coating

When cold spraying is performed at a velocity equivalent to or greater than a specific material-dependent critical velocity, powders suffer intensive plastic deformation and localized heating of
