According to the Wiki article, “Cold spraying was developed in the 1990. While experimenting with the particle erosion of the target, which was exposed to a two-phase high-velocity flow of fine powder in a wind tunnel, scientists observed accidental rapid formation of coatings. This coating technique was commercialized in the 1990s.”
So the tech has been around commercially for almost 25 years. The article in this post is quite vague about what ARL is having Rowan University do.
Has anybody heard of Rowan before? That’s a new one for me.
Not familiar with it either. In New Jersey.
So already commercialized? Not much of a step to manufacturing I should think.
Before 1990 there was a spray metal product called Eutectic (sp) but it was not a cold applied material though it was not very high temperature. Supposed to have been developed about 1906.
“So the tech has been around commercially for almost 25 years. The article in this post is quite vague about what ARL is having Rowan University do.”
Exactly correct. As you mentioned it is very vague. As such I find the article worthless unless it mentions the stability of the materials under mechanical stress and heat.

Rowan was formerly known as Glassboro State College. The audio company I work for does sound reinforcement for the graduations. Small college that is becoming a respected school.
