The Ottawa laboratory is the only university lab in Canada with the machine used to accelerate the metallic powders to cover objects. |

Metallic coats are used to protect diverse materials against wear, abrasion, chemicals and high temperatures. For example, we find these types of coatings on the blades of gas turbines, in chemical reactors, and on metallic pieces exposed to wear and abrasion.
Bertrand Jodoin is developing a new technique to apply these protective layers.
The technique consists of accelerating fine metallic powders in a machine. Once accelerated, the powders are projected onto the object to be covered. Since the powders are going at a great speed (1 km per second), the metallic grains are deformed and adhere to the object, creating the desired protection.
