DEVELOPMENT OF A METHODOLOGY FOR SCRATCH TESTING COLD SPRAY COATINGS

Popis výsledku v původním jazyce

This contribution introduces a comprehensive methodology for evaluating cold spray coatings using scratch testing technique. Unlike traditional thermal spray coatings, cold spray coatings have not been systematically and thoroughly scratch tested, leading to a lack of experimental data and evaluation methods. The primary objective of this research is to evaluate the adhesion or cohesion strength of the coating and to study the damage mechanism. The methodology focuses on the systematic preparation of test procedures. The evaluation of individual scratch marks, performed using both light and electron microscopy, forms the basis for refining the testing methodology. This study addresses a gap in the field, offering a straightforward approach for assessing cold spray coatings. The presented methodology is based on ISO 27307 where the applicability for cold spray coatings is lacking, especially regarding the evaluation of the crack initiation site. Inconel 713LC coatings in as sprayed state showed low energetic ductile fracture represented by tiny and shallow dimples in specific regions of cracks. The quality of the substrate/coating interface was excellent with the adhesion strength correlating with a normal load of 75 N applied to a scratch test indenter.
