COATING EVALUATIONS

EVALUATION STANDARDS

Comprehensive Coating Qualification & Evaluation
At Yellowstone, we perform rigorous coating coupon qualifications to ensure coating integrity and performance. Our evaluation process includes:

Metallographic Analysis – to assess microstructure, bond quality, and coating consistency
Mechanical Property Testing – including hardness, adhesion, and wear resistance
Extensive Failure Analysis – identifying root causes and recommending engineering-driven solutions

These processes ensure our coatings meet or exceed performance expectations in the most demanding service conditions.
