Wear resistance of AISI 304 stainless steel submitted to low temperature plasma carburizing

Abstract

Despite the AISI 304 stainless steel has high corrosion/oxidation resistance, its tribological properties are poor, being one of the barriers for use in severe wear applications. Thus, there is a wide field for studying technologies that aim to increase the surface hardness and wear resistance of this material. In this work, hardness and wear resistance for AISI 304 stainless steel submitted to the thermochemical treatment by low temperature plasma carburizing (LTPC) in a fixed gas mixture composition of 93% H 2 and 7% CH 4 are presented. Through the evaluation of the carburizing layers, it was possible to observe a substantial improvement in tribological properties after all temperature and time of treatment. This improvement is directly related to the increase of the process variables; among them temperature has a stronger influence on the wear resistance obtained using LTPC process.

The correlation between friction coefficient and areal topography parameters for AISI 304 steel sliding against AISI 52100 steel

“…They reported that SMA treatment is effective in reducing material removal by 2 to 4 times under all combined sliding wear and electrochemical conditions due to surface and sub-surface hardening effect induced by SMA process. Improved tribological properties have been found for low-temperature plasma carburizing (LTPC) treated AISI 304 during pin-on-disc wear test [14]. Previously, 2D parameters such as root mean square roughness (R q ), skewness (R sk ), and kurtosis (R ku ) have been used for characterizing the worn surfaces.…”

Determination of the construction material for phononic band gap structures by tribological performance

“…Compared to 303 steel, abrasive wear is more dominant compared to adhesive wear mechanism which can be seen explicitly in Figure 2a. Grooves are formed due to scratches of debris and adhesive wear is overwhelmed [25][26][27]. A mild adhesive wear can be related with metal removal zones on the wear surface.…”

Damage Analysis of Tattoo Needle Tips

“…As a result of the study, it was found that the material of the needles is not made of 316L commercially marked austenitic stainless steel, but of a more general, not very biocompatible alloy, 1.4301 steel. The stress of stabbing the skin is abrasive, the wear properties of these steel types are not outstanding [11,12]. Poor wear resistance in medical devices is unfavourable, as particles detached during the wear process can cause irritation if they enter the body, especially the two main alloys of the steel type: chromium and nickel [13].…”
