Degradation behaviour of boronized carbon and high alloy steels in molten aluminium and zinc

Effect of Fe 2 B orientation on erosion–corrosion behavior of Fe–3.5 wt.% B steel in flowing zinc

“…Therefore, the failure of the columnar Fe 2 B boride in the vertical sample stems mainly from corrosion, and not spallation, due to the pinning effect of oriented Fe 2 B boride and the corrosion products (mainly. FeZn 10 and FeZn 13 ).…”

“…Many studies have shown that a boronizing treatment can improve the corrosion resistance of the material to molten zinc; this resistance stems from the formation of Fe 2 B and FeB intermetallic phases in the surface of the material [11][12][13]. However, a boronizing layer is always prone to spalling, and hence its used in galvanizing is limited.…”

Thermal-Sprayed Coatings on Bushing and Sleeve-Pipe Surfaces in Continuous Galvanizing Sinking Roller Production Line Applications

“…To improve the service life of bushings and sleeve pipes as well as to reduce economic losses, many methods had been chosen to improve their wear resistance and anti-corrosion, such as selecting specialty materials, using a surface hardening process or other methods. The choice of materials usually includes high nickel (Ni)-chromium (Cr) stainless steel, Ni-based alloys or cobalt (Co)-based alloys for creation, but it obviously leads to higher manufacturing costs [10][11][12][13]. The method of material surface infiltration and centrifugal casting for the preparation of the bushings and sleeve pipes with a composite structure is a way to reduce the production cost and maintain excellent performance, but the manufacturing process is also very complex.…”

Effect of micro alloying elements on the interfacial reactions between molten aluminum alloy and tool steel

“…In this process, molten aluminum welds to the die surface and damages it during the ejection of casting from die [17,20,23,24]. Various factors influence the reactions at the interface of die steel and molten aluminum [6][7][8][9][10]24,25] such as: temperature and chemistry of the die and melt, and the surface engineering and coatings. There is research done related to modifying the chemical composition of the melt using alloying elements and applying coatings on die surfaces in order to reduce the formation of intermetallic layers.…”
