“…Arola et al (2001) investigated the effects of treatment parameters on residual stresses resulting from PWJ and AWJ peening of Ti-6Al-4V using XRD method. It showed that in AWJ peening of Ti-6Al-4V the magnitude of compressive residual stress in the material increased with a decrease in jet pressure and abrasive size which is in accordance with Arola and McCain (2000), while in PWJ peening of the same material the compressive residual stress increased with an increase in jet pressure.…”

Removal of heat-formed coating from a titanium alloy using high pressure waterjet: Influence of machining parameters on surface texture and residual stress. Journal of Materials Processing Technology, 223, Additional Information:• This paper was accepted for publication in the journal Journal of Materials AbstractTitanium alloys are widely used in aerospace and medical industries owing to high strength to weight ratio and outstanding corrosion resistance. A problem for titanium or titanium alloys is the existence of a hard, brittle and oxygen-enriched layer on the surface (so called alpha case) which is usually formed during hot forming processes or after long-term service at elevated temperatures in an open-air environment. With the development of waterjet system, high pressure waterjet has shown its capability for the removal of such hard and difficult-tomachine coatings. Waterjet machining is usually associated with a surface roughening effect due to the repetitive impacts of droplets. Surface roughening is unwanted for most of aerospace applications as rough surface is detrimental to the fatigue behavior of components, but is beneficial for medical application where fixation is required (e.g. metal orthopedic implants). An additional benefit of waterjet material removal is that the repetitive droplet impacts may introduce compressive residual stress to the machined surface and subsurface layers. In this study, Ti-6Al-4V with alpha case layer was subjected to plain waterjet over a range of parametric conditions. The completeness of alpha case removal was characterized by the depth of removal. The textured surfaces were quantified in terms of average surface roughness (Ra) and apparent volume for interdigitation (V i ). The magnitude of residual stress of PWJ-machined surfaces was measured using X-ray diffraction (XRD). ANOVA analysis was also conducted to identify the relative significance of machining parameters to the process outputs. It was found that an increase in removal depth results in an increase in the surface roughness as well as the interdigitation volume regardless of machining conditions. A compressive residual stress (-563 MPa~ -13 MPa) was found within all PWJ-machined surfaces. It was concluded that a maximum compressive residual stress simultaneous to a

“…The water jet is used for momentum transfer and to aid in removal of surface debris. The effects of AWJ peening surface treatments on commercially pure titanium (cpTi) and a titanium alloy (Ti-6Al-4V) have been examined experimentally (Arola and McCain, 2000;Arola et al, 2002). Through these studies it was found that the surface roughness increased with jet 172 Arola and Hall ORDER REPRINTS pressure and particle size, resulting in surfaces with much larger roughness than possible through pure WJ peening.…”

The abrasive waterjet (AWJ) has primarily been used for net-shape sectioning of engineering materials. In this study an AWJ was adopted for the surface treatment of commercially pure titanium (cpTi) and the contribution of treatment parameters to material removal and the deposition of particles within the substrate were examined. The surface texture and material removal rate were analyzed using conventional techniques whereas the quantity of abrasive particles embedded within the cpTi surfaces was determined using energy dispersive X-ray analysis (EDXA). Parametric effects related to particle hardness were distinguished from a comparison of surfaces treated with Aluminum oxide, garnet, and crushed glass abrasives. According to an analysis of variance (ANOVA), treatment responses were found to be primarily dependent on the abrasive size, abrasive hardness, angle of incidence, and jet pressure. The minimum and maximum concentration of particles embedded in the AWJ treated cpTi (in percent surface area covered) was 2.5 and 21.6%, respectively. Particle concentration and mean particle size in the cpTi increased with abrasive size, angle of incidence and jet pressure; the particle concentration reached saturation at an angle of incidence near 80 . Although abrasive hardness was important to the ORDER REPRINTS treatment responses, an increase in hardness beyond 800 on the Rosiwal scale resulted in minimal changes in material removal or other features of the process.

“…This process, presented in the literature as AWJP -abrasive waterjet peening, is a machining method which utilizes controlled hydrodynamic erosion, whereby the topography of the surface can be changed to give it the desired roughness, with a high degree of purification. Simultaneously with the change of topography, the hardened top layer of the material is obtained by introducing residual compression stresses [1].…”

The paper presents the results of a comparative study of shear strength of single-lap adhesive joints, depending on the method of surface preparation of steel plates with increased corrosion resistance. The method of preparing adherend surfaces is often one of the most important factors determining the strength of adhesive joints. Appropriate geometric surface development and cleaning of the surface enhances adhesion forces between adherend material and adhesive. One of the methods of shaping engineering materials is waterjet cutting, which in the AWJP -abrasive waterjet peening variant, serves to shape flat surfaces of the material by changing the roughness and introducing stresses into the surface layer. These changes are valuable when preparing adhesive joints. In the study, surface roughness parameters obtained with AWJP treatment, were analyzed in direct relation to the strength of the adhesive joint. As a consequence of the experimental results analysis, the increase in the strength of the adhesive joints was observed in a certain range of parameters used for AWJP treatment. A decrease in shear strength of adhesive joint with the most modified topography of overlap surface was observed.
