Experimental Evaluation of 100Cr6 Steel Microindented Surfaces Under Lubricated Nonconformal Point Contacts

Advanced Engineering Materials, EarlyView.
The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Enhancement of wear properties of a polyether ether ketone polymer by incorporation of carbon and glass fibers [PDF]

, 2019
Some properties of polymers can be improved through the incorporation of carbon and glass fibers into the polymer matrix. In this research, the wear resistance of two polymer composites CF-polyether ether ketone (PEEK) and GF-PEEK were compared with the ...

Characterization of Macro/Microstructure and Corrosion Resistance of Austenitic Gas Tungsten Arc Welding Cladding

Advanced Engineering Materials, EarlyView.
Cladding is a proven method that boosts the surface qualities of mechanical parts by applying a layer of more durable material over a base substrate. This work responds to the needs of offshore and pressure vessels sectors by focusing on cladding a super austenitic steel onto low‐carbon steel through gas tungsten arc welding.

Calculation of wear (f.i. wear modulus) in the plastic cup of a hip joint prosthesis [PDF]

, 1975
The wear equation is applied to the wear process in a hip joint prosthesis and a wear modulus is defined. The sliding distance, wear modulus, wear volume, wear area, contact angle and the maximum normal stress were calculated and the theoretical ...

Study of the sliding wear in bronzes

Revista Facultad de Ingeniería Universidad de Antioquia, 2014
Three bronzes were evaluated: SAE 67, national and american typically used like bearing material in the sugar cane mills. Sliding wear tests were made under the G77 standard, using bronze blocks, SAE 1045 steel ring and oil like lubricant. The tribometer was calibrated using SAE 4620 steel ring and tool steel SAE O1 was used for the blocks ...

Prediction the wear of sliding bearings

International Journal of Engineering & Technology, 2018
The problem of developing a calculation-experimental method for calculating wear of a sliding bearing based on a two-factor wear model (contact pressure - sliding velocity) with identification of wear resistance parameters was considered. On the basis of the proposed wear model, the wear-contact problem for a cylindrical sliding bearing was solved. The
