Montreal Carbide adheres to the highest quality control system, and have adopted some of the most stringent QA/QC system in the world. As such, we have been qualified as a Material Control at Source supplier (MCS supplier) for Pratt and Whitney Canada since 1990. We have been qualified by PWA as a Laboratory Control at Source supplier (LCS supplier) since 2000. We are approved for manufacturing many powders and certifying them to Pratt and Whitney specs.

A first approval was also recently obtained from the Rolls Royce Corporation (Formerly known as Allison Engines) and we are working on several fronts to obtain more approvals from different OEM in the world.

Special importance is given to reproducibility. We put a big emphasis on finding preferred values within tolerated boundaries of a specification and making powders to these preferred values. We have a long track record of lot after lot success and repeatibility. Since there are so many parameters in thermal spray that vary over time, it is comforting to know that you are getting a powder that works from lot to lot without having to do so many adjustments. When required, we are able to produce large lots of powders (over 5000 lbs).

We use the following testing procedures to insure the highest quality material only are delivered to customers:

Particle size analysis
X-Ray Diffraction
Infrared Spectroscopy
Chemical Analysis

(Microtrac, sonic sieve, ro-tap)
(morphology and visual tests)
(metallurgical phase analysis)
(complex chemical composition)
(chemical composition)
