“…The 0.75 μm thick coating improved rolling contact FL while the 1.47 and 2.08 μm thick coatings showed worse rolling contact fatigue resistance. 39 Middleton et al 15 found that 1 µm thick TiN coatings on M50 steel improved the L 50 life nearly fourfold, while 0.25 µm thick coatings showed no improvement. Polonsky et al 23 found that the L 50 FL of M50 steel was increased by 2 to 3 times by TiN coatings with a optimum coating thickness of about 0.75 µm.…”

Rolling bearings are critical in automotive engines, wind turbine drive trains, and numerous other mechanical systems. Rolling bearings can suffer from early failures, which result in high operation and maintenance costs. Surface engineering techniques, such as the application of coatings and additives for lubricants have been developed to improve the tribological performance of rolling bearings. In this article, the performance of physical vapor deposition coatings on components working under rolling/sliding contacts and rolling bearings is reviewed. The applications of physical vapor deposition coatings in the rolling bearing industry are summarized. The effects of coating thickness, coating mechanical properties, test conditions, coating bonding layer, and coating architecture on coating performance are discussed. At the end of the article, possible approaches to further improve the performance of physical vapor deposition coatings on rolling bearings are proposed.

“…A further increase in need for high performance balls and roller bearing components that can withstand extreme applications has led to a growing interest in hard coatings for their better fatigue life and wear resistance. [9][10][11] In particular, hard TiN and TiC (N) coatings and also DLC films 12,13 have attracted and still attract much attention of manufacturers. Experiments conducted on compact materials showed that the hard coatings can effectively extend the fatigue life of steel bearings.…”

Investigation was focused on resistance of Astaloy CrL type sintered material to contact fatigue. The material in two versions (0·3 and 0·7 wt-%C) was covered with TiCN coating. The results show that resistance to contact fatigue increased substantially, up to the value of about 3410±90 MPa. This increase was influenced primarily by the properties of coating. In this case, the impact of the matrix was of secondary importance. The results obtained in the evaluation of life in terms of contact fatigue were confronted with those of the microscopic observation of generation and propagation of cracks leading to the formation of pitting, as well as with other tests. It describes the impact of contact fatigue stress to changes in the material at the point of application. A special section is devoted to the use of finite element method (FEM) for simulation of the Hertzian stress and changes during contact strain.

“…This work illustrates the need for improving the land wear resistance of the P675. Literature survey indicates that surface modification techniques, such as coatings [5][6][7], ion implantation [7,8], low plastic burnishing [9] and laser surface texturing [10] can be applied to enhance the wear resistance of the land surface.…”

State-of-the-art bearing materials, such as Pyrowear 675(P675) have been developed to meet the requirements of the next generation of gas turbine engines. P675 bearings have exhibited higher land wear compared to conventional M50 bearings under contaminated test conditions. Surface modification techniques can be applied to enhance the wear resistance of bearing land surfaces. A coating has been developed to minimize abrasive wear of land surfaces. A new procedure using a 40 mm bearing test rig has been developed to effectively evaluate land wear under simulated contaminated condition. Test conditions including contamination concentration, test duration, test temperature and lubricant flow rate were optimized to obtain measureable wear on the land surfaces in a reasonable test time. Results obtained using M50 Nil, P675 and M50 bearings are presented to illustrate the viability of the test procedure.
