A novel two-step process for enhancing adhesion strength of cold-spray metallization of carbon fiber-reinforced plastics

Materials & Design
Cold-spray processing is a promising technique for the metallization of carbon fiber-reinforced plastics (CFRPs). However, the adhesion between the cold-sprayed metal deposits and CFRP substrate needs to be improved.

Evaluation of Melting Efficiency in Cold Wire Gas Metal Arc Welding Using 1020 Steel as Substrate

Metals
A key welding parameter to quantify in the welding process is the ratio of the heat required to melt the weld metal versus the total energy delivered to the weld, and this is referred to as the melting efficiency.

Cold gas dynamic spraying of titanium coatings [PDF]

, 2008
Cold gas dynamic spraying, CGDS, is a relatively new technique used to deposit materials onto the surface of a substrate. It differs to the majority of other thermal spray techniques as the substrate and particles are not exposed to high temperatures during the spraying process.
