“…This methodology is currently used in some nonferrous alloys with the addition of chromium, as well as in guide mandrels (piercing plug made of alloyed steel) used in the rolling process of seamless steel pipes, for example. [32][33][34][35][36] In this sense, considering the relatively high Cr content in the evaluated steel, compared to common carbon and low-alloy ones, and envisioning the possibility to use similar mechanism seeking to improve the wear behavior of the studied low-cost stainless steel for some applications as, for example, open train wagons and sugarcane industry components, where a relatively thick layer of compact oxides would not generate any other type of inconvenience, this pioneering evaluation about the effectiveness of a thick oxide film on the wear behavior of the studied stainless steel is valid. Therefore, initially it is of great importance to characterize the effect of isothermal heat treatments on the surficial oxidation characteristics, aiming to describe its kinetics and the oxide layer characteristics.…”

The UNS S41003 ferritic stainless steel is a low‐carbon alloy that has great corrosion and oxidation performances in wet and aqueous environments, as well as it has high mechanical strength and ductility when compared to the most ordinary low‐carbon steels. These great characteristics, allied to its relatively low manufacturing cost, have made it a potential option to replace structural steels in many applications. Although it is a current trend, there are still few published studies that relate this steel manufacturing process with microstructural evolution and mechanical behavior, mainly regarding its wear behavior, which is a substantial and sometimes limiting characteristic for its applications. In this context, this article presents a pioneering study about the use of biphasic microstructures (ferrite–martensite) and controlled surficial oxidation to enrich the wear behavior of a UNS S41003 steel type. This study concludes that, if well planned, both the increase of martensite fraction and the controlled growth of an adherent and compact oxide layer on the steel surface significantly improve its wear performance, decreasing its wear rate up to 93%.

“…The third layer was characterized by an elevated aluminum content and its thickness was 12, 10, and 9 µm for the PEO coatings on the Al, Al + 1% Cu, and Al + 4.5% Cu composites, respectively. Note that NBS spectrometry gives a mass thickness, i.e., the porosity of the coating is not considered [10,25].…”

“…The main layer of PEO coatings on aluminum alloys, generally, includes the corundum, α-Al 2 O 3 , which has high microhardness and provides good wear resistance [10,11,[18][19][20][21]. In particular, aluminum alloys with PEO coatings have a high wear resistance under sliding friction [22][23][24][25][26][27].…”

Coatings, with a thickness of up to 75 µm, were formed by plasma electrolytic oxidation (PEO) under the alternating current electrical mode in a silicate-alkaline electrolyte on aluminum composites without additives and alloyed with copper (1-4.5%). The coatings' structure was analyzed by scanning electron microscopy, X-ray microanalysis, X-ray photoelectron spectroscopy, nuclear backscattering spectrometry, and XRD analysis. The coatings formed for 60 min were characterized by excessive aluminum content and the presence of low-temperature modifications of alumina γ-Al 2 O 3 and η-Al 2 O 3. The coatings formed for 180 min additionally contained high-temperature corundum α-Al 2 O 3 , and aluminum inclusions were absent. The electrochemical behavior of coated composites and uncoated ones in 3% NaCl was studied. Alloyage of aluminum composites with copper increased the corrosion current density. Plasma electrolytic oxidation reduced it several times.
