THERMAL, PLASMA, AND HVOF SPRAY COATINGS EVALUATION

Metallurgical Examinations of Coatings/Substrate Combinations

thermal spray-5-650

The aerospace industry relies on thermal spray coatings to ensure durability of parts that will be subjected to wear, high heat, corrosion and other harsh in-service conditions. Proper composition and application of thermal spray coatings is critical to safety and reliability in planes, helicopters and other aerospace applications.
 
The main source of error in metallographic evaluation of thermally sprayed coatings and interpretation of test results is the damage that could occur during sample preparation for the analysis. Sample preparation involves sample sectioning, cleaning, mounting, grinding (planar and fine) and polishing (rough and final).
 
IMR Test Labs performs routine and advanced coating metallography examinations on thermal spray, plasma spray and diffusion coatings.  We support R&D efforts, provide overflow testing, perform failure analyses and production control testing for most of the major aerospace OEMs.
 
 

 

GE ACCREDITED CENTRAL COATINGS LAB - CCLthermal spray-6-450

IMR Test Labs – Singapore is now approved by GE Aviation as a Central Coatings Laboratory (CCL).  Suppliers who have been approved to add the following coating types and class to their current GT193 may send their round robin samples to IMR Singapore (see the list of coatings below for specifics).  More coatings will be added to this list in the future as they get approved by GE Aviation.

IMR Test Labs - Singapore carries GE S-400 Code AJ approval on cert T9325, which includes the coatings listed below.

 

 

Pratt & Whitney Coatings Evaluation Approvalthermal spray-1-cropped

IMR has long offered our popular Aerospace Coatings and Metallography course to industry.  A key feature of this course is that Pratt & Whitney requires their coatings suppliers to have their metallographers pass this course in order to evaluate their Pratt coatings.
 
More recently, as a result of our demonstrated high level of expertise with these coatings, IMR Test Labs’ Ithaca location became the first independent lab ever to be awarded Code 7i approval by Pratt & Whitney.  This unique approval allows coatings vendors to send their Qualification samples to IMR for review.
