“…erefore, surface treatments for obtaining NCS and UFGS are used more widely. Low-frequency and high-frequency vibration hardening with the balls (VHB) in a special bunker [1][2][3][4][5][6][7][8] are among the known SPD methods of technological improvement of machine components surfaces. However, a depth up to 100 μm of hardened surface layer is insignificant [9], and it does not allow additional finishing operations for high-precision components.…”

The vibration-centrifugal hardening forms a gradient ultrafine grain structure of the ferritic class with a grain size of 190 nm and a surface microhardness of 8.9 GPa and a depth of up to 6 mm on the surface of 40 Kh steel of the ferritic-pearlitic structure. These parameters are formed due to an increase in the mass of the tool that acts on the processed surface through the balls and depend on the treatment modes. This surface ultrafine grain structure increases the wear resistance properties of steel in oil and oil-abrasive environment and improves the electrochemical characteristics.

“…They observed an increase of 144% in hardness and hardening depth of 450 µm after UIP. Zhu et al [ 84 ] conducted UIP experiment on pure Ti and demonstrated the effect of peening distance, peening duration, and shot diameter on surface hardness and microstructure. Their study concluded that with an increase of peening duration and shot diameter, surface hardness increases, whereas it decreases with the increase of peening distance.…”

Surface modification methods have been applied to metals and alloys to change the surface integrity, obtain superior mechanical properties, and improve service life irrespective of the field of application. In this review paper, current state-of-the-art of peening techniques are demonstrated. More specifically, classical and advanced shot peening (SP), ultrasonic impact peening (UIP), and laser shock peening (LSP) have been discussed. The effect of these techniques on mechanical properties, such as hardness, wear resistance, fatigue life, surface roughness, and corrosion resistance of various metals and alloys, are discussed. This study also reports the comparisons, advantages, challenges, and potential applications of these processes.

Type 316 stainless steel is a material that is often used in the medical world, especially as a material for making bone implant plates. However, the use of stainless steel as an implant material, stainless steel must be treated to increase the hardness and adjust the level of roughness on the surface. In this study, shot peening was carried out on the 316 stainless steel surface. The shooting parameters used were 2, 4, 6 minutes for the shooting duration, and 0o, 15o, 30o, 45o for the shooting angle, as well as the diameter of the steel shot used, i.e. 0.6 mm and 1 mm. The results of this study indicated that there was a change in the characteristic properties of 316 stainless steel, namely the hardness and surface roughness.
