For corrosion-resistant layer formation, a method using only hot water under atmospheric pressure has been developed. A was obtained with shot peening treatment sodium bicarbonate media as pre-process that is activation by formation of plastic strain on the surface.

Transmission engineering components need to fulfill requirements for adequate wear resistance and fatigue resistance, which are related their surface properties. In this paper, we combined shot peening nitrogen ion implantation improve the properties of 16Cr3NiWMoVNbE gear steel. The average roughness decreased slightly after because high-speed impact implanted ions having etching role. maximum...

The industrial world is currently growing rapidly. need for JIS S45C as a structural steel increasing which used to manufacture machine components. Efforts improve the mechanical properties of can use heat treatment and surface treatment. One treatments that often in shot peening. This study aims determine effect annealing peening on steel. indicated by changes results both transverse hardness ...

Pitting and wear often appear on heavy-duty-axle gears due to their harsh working conditions, such as high torques, loads, poor lubrication. Shot peening is a popular surface strengthening method for gears. In order ensure complete coverage during shot peening, 100~200% usually prescribed most However, it difficult effectively improve the contact fatigue resistance of Generally, increasing can ...

In order to develop the technique predict surface characteristics of fatigue specimens austenitic stainless steels by controlling finishing processing lathe turning and shot peening, applicability response models formerly created present authors using experimental design experiments approaches with different types and/or rolling conditions have been investigated. The conclusive remarks could be...

Metal dusting attack is a serious problem in processing industries using carbonaceous gases and high temperatures. Ni-based alloy 699 XA was recently developed as an for these types of environments with resistance against metal dusting. In this study, different surface treatments chromium- aluminum-rich are shown to have important influence on the onset behavior. It found that traditionally con...

Abstract Severe plastic deformation methods like shot peening (SP) are known as efficient surface treatments and grain refining processes which afford more effective properties in metallic materials. In the current research, a comprehensive study was carried out on SP of AISI 316 L steel. It included 42 different with wide range Almen intensities 12–27 A various coverage degrees (100%–1500%). S...
