“…Ha a króm tartalom a passziválási érték alá süllyed (körülbelül 12 tömeg %) az acél korróziós szempontból gyengül [5,6], ebben az állapotban érzékennyé válik a szemcseközi korrózióra és a feszültségkorrózió okozta repedésre. Az acél korrózióállóságának csökkenése bekövetkezhet hőkezelés során, ha a hűtés a homogenizálási hőmérsékletről kis sebességgel történik vagy hegesztési folyamat közben (hőhatásövezet jelenléte) vagy melegalakítás során is.…”

The process of the secondary phases precipitation controls the mechanical and physical properties of the stainless steels. The goal of this analysis is characterisation of the chosen factors (temperature expositions and deformation) influencing kinetics of the secondary phases precipitation at the grain boundaries. The improvement of the commercial steel properties relies on an accurate prediction of the microstructure. Összefoglalás:A másodlagos fázis kiválása befolyásolja a korrózióálló acél mechanikai és a fizikai tulajdonságait. A tanulmány célja megvizsgálni adott tényezők (hőkezelés, maradó alakváltozás) hatását a másodlagos fázis kiválásának kinetikájára a szemcsehatáron. Az acélok tulajdonságainak javításához szükséges a kialakuló mikroszerkezet pontos ismerete.

“…Further research on the FS of martensitic stainless steels was reported by Puli et al [19], with special focus on shear and bend testing. Puli et al [20] also highlighted the deposition of AISI 316L on the mild steel substrate. According to their study, microscopy measurements revealed numerous stacking faults and high dislocation density, as anticipated considering the extensive plastic deformation involved in the FS process.…”

SummaryNowadays friction surfacing (FS) has become a popular solid state surface coating technology suitable for a range of substrates. The technology has the ability to produce coatings with marginal dilution and good metallurgical bonding. The present study has aimed at producing a single-track and a three-track overlapping coatings on high-speed steel substrates using an AISI 316 consumable rod. Microhardness of coatings was examined by a Vickers micro hardness tester. Coatings of all the friction surfaced samples in as-deposited condition showed significant hardness. The infrared thermography showed that the peak temperature achieved by the AISI 316 coating was about 1020 ͦ C. The coatings, thus attained, were further analysed for their microstructural features and interfacial characteristics by using FE-SEM. The EDX analysis showed the presence of nickel, chromium and oxygen, which indicates the formation of oxide compounds. The formation of AISI 316 deposits on the HSS substrate and the effect of coating overlapping are discussed in this article.

“…As an important surface engineering technique, surface overlaying, which can obtain a large-scale interface with high metallurgical binding strength to substrate materials, has been widely used to repair various damaged surfaces or deposit different coatings on vulnerable surfaces owing to its high efficiency, low cost, and good applicability with substrate materials [2][3][4][5]. Existing investigations Considering the mechanical properties, low cost and low environmental impact together with good compatibility and firm combination with the substrate, a novel iron-based alloy composition Coatings 2019, 9,804 3 of 14 based upon the Fe-(Cr, Mo)-C-(B, P) alloy system was designed in the current work.…”

Wear failures of components often occur and cause great economic losses in modern industry production. To obtain excellent wear resistance surface will help reduce the abrasion. Herein, a wear-resistant iron-based alloy coating was deposited on a low-carbon steel substrate by argon arc overlaying, and sequentially surface nanocrystallized through ultrasonic impact treatment (UIT). Micro-structural, mechanical property (including nanohardness and elastic modulus) and wear behavior changes of the coating before and after UIT were experimentally investigated. In addition, the wear mechanism variation owing to the application of UIT was discussed. The results show that a highly deformed nanocrystalline layer with an average grain size in the range of~100 nm was generated at a depth of approximately 34 µm from the treated coating surface, which contains a certain amount of the deformation-induced α'-martensite phase. Compared with the as-deposited coating, the coating after UIT processing exhibits considerable improvements in the ratio of nanohardness (H) to elastic modulus (E) and better wear resistance under the same wear test conditions. The wear mechanism has also changed from the adhesive type of the as-deposited coating to an abrasive type on the introduction of a nanocrystalline microstructure.have demonstrated that coatings with thicknesses on the order of millimeters produced by argon arc surfacing welding exhibit a dense microstructure, excellent strength and toughness as well as high wear resistance. Such coatings can even replace entire components and significantly improve the wear resistance [6]. Iron-based alloys known as their low cost and excellent comprehensive properties have drawn much attention and shown great potential application in different fields of industries [7,8]. Therefore, iron-based alloy coating on easy wear parts and components has positive contribution to extend their service life and improve their service performance. Unfortunately, high residual stress and deformation introduced during overlaying may change the shape and the size of components, which limits their use in certain demanding conditions. In this sense, appropriate surface treatment is crucial for the performance improvement of overlaying coating.Surface nanocrystallization owing to their unique microstructural characteristics exhibits superior physical, chemical, and mechanical properties and have attracted considerable interest as a viable alternative in protection applications [9]. Thus, surface nanocrystallization techniques such as surface mechanical attrition treatment (SMAT) [9], shot peening (SP) [10], hammer peening [11], laser shock peening (LSP) [12] and ultrasonic impact treatment (UIT) [13] are more attractive and expected to present new ideas to realize materials' nanostructured layer in various surface protection applications.Compared with the other mechanical surface treatment techniques mentioned above, it is demonstrated that the UIT is more convenient and economical and controllable to rapidly realize s...
