Fabrication of TiN coatings using mechanical milling techniques

Effect of annealing treatment on the structure and properties of the nanograined TiN coatings produced by ultrasonic-based coating process

“…The TiN coatings were chosen as a representative example. Our first attempt revealed that nanostructured TiN coating with good adhesion can be formed by UMCA method on the steel, Ti, and Al substrates [4]. The properties of the coatings should be improved.…”

“…The ultrasonic mechanical coating and armouring (UMCA) process may provide a simple and effective procedure for the coating fabrication [1][2][3][4]. One of the attractive features of this process is that it can be carried out at room temperature and atmospheric pressure, and the combined effects of surface modification (such as cold-hardening), mechanical activation, and nanocrystallization of substrates can be achieved by this coating treatment in just one operation.…”

Sliding wear behavior of FeCrC reinforced and Ni-based composites produced by mechanical alloying technique

“…The method is guided by principle indicating that on top of the vibration compartment should be a fixed substrate while the powder and ball should be weighted into it. The coating forms as a result of the powder particles being cold welded to the surface as well as the ball causing an impact on the substrate's surface [4,5]. The critical feature that defines the process is when the ball comes across the condensed grain structure to the nanometer scale.…”

Effect of process parameters on the formation of Ti–Al coatings fabricated by mechanical milling

“…This method has been applied for fabricating Ni-Al and Fe-Al coatings; similar structures and tendencies in the coating formation for these systems to those for the Ti-Al system were observed [1,2,[4][5]. Furthermore, the method has been successfully used for depositing hard coatings such as TiN and TiC/TiN on different substrates [6,7]. It is noteworthy that the special chamber, which is designed so that the substrate is fixed at the top, allows uniform coatings to be produced on substrates 10 cm long.…”
