The friction surfacing process enables deposition of a wide variety of high-specification materials with an ideal metallurgical bond onto a range of metal substrates. This article provides a process description and discusses the equipment used for, and the applications of, friction surfacing.

In the friction surfacing process, a rotating consumable is brought into contact with a moving substrate, which results in a deposited layer on the substrate. This article describes the process as well as the equipment used. It also provides information on the applications of the friction surface process.

This article discusses the application of friction stir processing (FSP) and friction surfacing for tribological components. It describes the three critical aspects involved in the application of FSP for near-surface material modifications intended for tribological applications. These include tools, processing parameters, and machines. The article also discusses the equipment and processing parameters for friction surfacing. It describes various hybrid stir processing techniques that involve preheating of the workpiece material, especially relatively hard and high-strength ones. The article presents a partial list of surface-modification methods based on FSP. The partial list includes surface hardening, surface composites, and additive coating. The article also provides information on generation of residual stresses in metallic materials and alloys form different variants of FSP.

This article begins with the basic concept of friction and with the general approaches that can be used to control or minimize it. It focuses on the factors influencing rolling friction: surface topography, composition, subsurface microstructure, and lubrication conditions. The article reviews the microscopic mechanisms generating friction. It concludes by discussing the three components of rolling friction: microslip at the interface, anelastic hyteresis losses, and surface roughness.

This article describes the laboratory techniques for direct measurement and quantification of die wear in verifying a proprietary die-wear predictor methodology. This method is based on a theoretical formula that can be used to predict the rate of die wear and the life of a die surface coating, applicable to both mild steel and high-strength steels stampings. The article discusses the behavior of the surface conditions through quantitative measurements and surface analyses conducted throughout the wear tests. The surface conditions include surface roughness, surface morphology, microstructure, interfacial friction, surface temperatures, and wear rate.
