“…For an applied load of 0.49 N, there is a decrease of 45% in the wear coefficient with the increase in the abrasive slurry concentration. If compared with our previous work [28], which were obtained under exactly the same experimental conditions, the boroniobized AISI 1020 steel showed higher values of wear coefficient than untreated and borided samples. For comparison purposes, the highest wear coefficient obtained for untreated AISI 1020 steel samples was 3.59×10 −3 ±8.79×10 −5 mm 3 Nm −1 [28], which is only approximately 9% higher than the lowest wear coefficient obtained for boroniobized samples.…”

“…Despite the roughness increase in relation to the untreated condition, if compared with the borided condition described in [28], the boro-niobized samples presented statistically the same roughness values. A low roughness variation occurs between these two conditions.…”

“…The initial roughnesses, before boro-niobizing treatment, were 0.02±8×10 −4 μm for the average surface roughness (Ra) and 0.03±3×10 −3 μm for the root mean square roughness (Rq). Skewness (Rsk) and kurtosis (Rku) were −0.87±0.67 and 9.30±3.39, respectively [28]. After the boro-niobizing treatment, the surface roughness increased to: 0.96±0.05 μm (Ra), 1.42±0.08 μm (Rq), 1.23±0.20 (Rsk) and 8.16±1.12 (Rku).…”

“…Thus, in the present study, multicomponent boriding was carried out on AISI 1020 steel in order to obtain a niobium boride surface layer. The surface roughness, microstructure, microhardness and microabrasive wear behavior were examined and the results were compared with that of untreated steel results from our previous work [28]. This investigation can elucidate important questions about the abrasive wear behavior of niobium boride coated low carbon steels and contribute to the expansion of the application field of these steels.…”

Niobium boride coating was produced on AISI 1020 steel by multicomponent boriding process. Boriding treatment at1000°C for 4 h was followed by thermo-reactive diffusion technique at 1000°C for 6 h under argon atmosphere. Microabrasive wear tests were carried out using SiC abrasive particles at slurry concentrations of 0.5 and 1.0 g cm −3 . Normal loads of 0.49 and 0.98 N were used. NbB and Nb 5 B 6 phases were identified by XRD analysis. The niobium boride coating thickness was 2.0±0.5 μm and its hardness was 1360±200 HK 0.01 . Owing to the presence of a porous region on the niobium/iron boride layers the abrasive wear resistance decreased comparing to the borided and untreated AISI 1020 steel. Rolling abrasion was the main wear mechanism observed.

Boriding is the process of coating the metal surface with a ceramic metal boride layer by the diffusion method. Iron borides, one of the metal borides, are called ceramics because they are covalently bonded compounds. Iron boride coatings contain strong Fe-B and B-B covalent bonds. In this study, the effect of boronizing on the corrosion resistance of AISI 1010 steel was investigated. Baybora-1 which has recently been patented was used as boronizing agent. AISI 1010 steel was borided at 950°C for 2, 4, and 6 h using the solid method. The microstructure, hardness, and corrosion rate of the samples were investigated. The change in the corrosion rate of the samples was determined by the corrosion test specified in the ASTM G31-72 standard.The results showed that the hardness of the iron boride layer formed on the surface as a result of the boronizing process was greater than that of the matrix. As a result of the boriding process, the hardness of the iron boride layer on the steel surface reached approximately eight times the hardness of the substrate matrix. The thickness of the iron boride layer on the steel sample surface was measured at 950°C for 2 and 6 h, respectively, as 45 ± 12 and 155 ± 13 µm. It was concluded that the boriding process increased the corrosion resistance of steel.

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%.
