Characterization of tribological conditions within direct hot stamping

High-temperature tribological performance of functionally graded Stellite 6/WC metal matrix composite coatings manufactured by laser-directed energy deposition

“…In hot stamping processes, the tool damage caused by wear and friction during the high-temperature forming process is a hindrance in terms of productivity and tool lifetime [4], and stems from the unavoidable contact between the tool and the processed blanks [6]. Unfortunately, conventional lubricants cannot be employed to counter these phenomena, as the temperature range of the manufacturing process is far outside the working range of most lubricants [7].…”

Effect of CeO2 on high-temperature wear resistance of WC/Fe-based coatings

“…The formed parts have the advantages of high bending strength, lightweight and high complexity, and are widely applied in the automotive field. The application of hot stamping technology has greatly improved the rigidity and strength of the car body's overall structure [4][5][6]. H13 hot-working die steel, owing to the advantages of high hot strength, toughness and hardenability, have been widely applied in casting dies, extrusion dies, and Hot stamping dies [7,8].…”

The effect of hot-stamping process on the local electrochemical behaviour of the 22 MnB5 steel coated with hot-dip aluminium-silicon

“…Since then, carmakers have been planning actions in order to meet the worldwide requirements to reduce greenhouse gas emissions [1]. Simultaneously, the safety of the new vehicles produced should be improved [10,14,38]. Among all strategies to combine sustainability-including environmentally friendly processes and products-and safety, the lightweight-design methods have been identified among the most efficient [3,14].…”
