“…The result showed that refined grain hardening layer and the compressive residual stress field can effectively prevent the crack initiation. Yao et al [9] used abrasive waterjet peening on TA19 alloy and found that nanoscale grains and abundant dislocations were generated on the work-hardened layer.…”

Abrasive waterjet peening is a favorable surface treatment method for improving the fatigue resistance of metal materials. An insight into the fatigue crack growth properties of AWJ peened specimens is meaningful for obtaining better strengthening performance. In present work, a numerical model of AWJ peening was established and experimentally validated for investigating the fatigue crack growth characteristics of Aluminum specimens. The effect of peening and loading conditions on the fatigue performance was also analyzed. The results indicated that the stress intensity factor at the peened region was enhanced and the crack propagation was significantly inhibited by the compressive residual stress. The influence of compressive residual stress on the effective stress factor range is greater under lower external load and higher loading ratio. The fatigue life for reaching the crack length of 40 mm is increased by 37%, 60% and 98% after peening by using the intensity of 0.6 mmA, 0.8 mmA and 1 mmA, respectively.

“…AWJ technology achieves uniform mixing before particles are ejected from the nozzle, and the high cluster energy of an AWJ is used to strengthen the key components of important equipment, thus causing dislocation slip, grain refinement, and plastic deformation in their tissues [4]. Consequently, a residual compressive stress field is formed [8], which can significantly improve the reliability and anti-fatigue life of the components [9] [10].…”

Abrasive water jet technology has been applied to strengthen the surfaces of complex shapes and high-strength components to improve their fatigue life. In this regard, the energy distribution affects the strengthening; hence, its uniformity must be comprehensively investigated. The main parameters affecting the energy-distribution uniformity are the particle performance parameters, particle velocity distribution, particle spatial distribution, and overlap. In this study, theoretical models of single-pass energy distribution and multipass lap energy distribution are established by considering the spatial and velocity distributions of particles. Additionally, the ratio of the energy difference to the maximum energy in the lap range is determined as the index of energy-distribution uniformity. Based on the relationship between deformation and energy, the theoretical model is verified using 18CrNiMo7-6 alloy steel. Results show that the maximum theoretical deformation in a single pass is consistent with the experimental results, with an error of less than 6%; additionally, the theoretical and experimental peak and trough differences after a multipass lap show good agreement. Using the proposed model, the lap distance can be obtained to guide practical engineering applications.

Titanium alloy is a widely used metal material, which can be applied in fields such as healthcare, petroleum exploration, aerospace, etc. In this paper, a new method for polishing the titanium alloy by a pulsating air jet is proposed. Compared with traditional abrasive jet polishing, this method has the advantages of simple structure, low nozzle wear, and high polishing flexibility. The working principle and material removal mechanism of the pulsating air jet polishing (PAJP) are introduced. Combined with orthogonal experiments, range analysis and variance analysis were used to find out the influence degree of each process parameter on the PAJP of titanium alloy, and the optimal level of each parameter was found. Through the experiments, a prediction model of surface roughness was established by regression analysis, and the predicted value was compared with the measured value. The maximum relative error of the prediction model was 10.3%, and the minimum relative error was 1.1%. The average relative error was 6.2%.
