Abstract
In this study, IF steel was coated by the low-pressure cold spray deposit method with different coating materials. Al, Ni, Zn, and Sn powders were used as coating matrix. All coating materials were reinforced by Al2O3 particles. Mechanical properties of the coatings were determined by three-point bending, scratch, wear tests, and hardness measurement. Micro-level defects and structure of coatings were examined by SEM, EDX, and Optical microscope analysis. All coatings were applied successfully, and the most distinct defects occurred in the Ni-matrix coating. The hardness of the Ni matrix coating was the highest, however the wear resistance was the highest for the Zn matrix coating. The lowest hardness and wear resistance were measured in the Sn matrix coating. As a result of the bending test, distinct crack formations were observed in the Zn matrix coating, unlike the others.
