Design methodology for optimized die coatings: The case for aluminum pressure die-casting

Thermal Fatigue of Die-Casting Dies: An Overview

“…Moreover, improving the surface properties of alloys and metals without any change in the bulk properties, like oxidation , hardness, corrosion, and corrosion resistance, and can show types of metal ions with an adjustable flow of ions and energy Indicates that the surface treatments of CrN coating also deposited with the planting of metal and carbon ions lead to condensation and phase shift in the nearsurface system to improve the corrosion resistance, abrasion resistance and fatigue strength significantly.Previous studies have suggested several methods to extend the service time of the casting dies such as nitriding [35], PVD/CVD coatings [36,37], and laser surface engineering [10,27,38,39]. The findings of studies carried out by Lin et al [40], Koneshlou et al [37] and Bronfin et al [26] recommended the use of four different layers to change the properties of metal in the best way possible [19] CONCLUSION This study identifies and exemplifies the die casting process and the defects which appear during the casting. Detail is then given of ferrous casting alloys and non-ferrous casting alloys.…”

Ejection Performance of Coated Core Pins Intended for Application on High Pressure Die Casting Tools for Aluminium Alloys Processing

“…In production of aluminium alloy castings by HPDC process the tool surfaces are exposed to harsh operating environment [1]. Although, these effects are reduced by application of die lubricant the tool surfaces wear due to erosion, soldering and thermal fatigue, which commonly act simultaneously [1,2].…”

“…Although, these effects are reduced by application of die lubricant the tool surfaces wear due to erosion, soldering and thermal fatigue, which commonly act simultaneously [1,2]. Due to wear, tool operation becomes difficult, production efficiency is reduced, castings lose tolerances and quality of their surface finish is reduced [3].…”

“…Therefore, diffusion layers, thin ceramic coatings and their RESEARCH combinations are applied for increasing the wear resistance of HPDC tools [1,2]. Coatings produced by physical vapor deposition (PVD) have a range of required mechanical properties and high chemical inertness in molten metals [1,2,5].…”

“…Coatings produced by physical vapor deposition (PVD) have a range of required mechanical properties and high chemical inertness in molten metals [1,2,5]. Ceramic coatings efficiently suppress different types of wear and especially the corrosion caused by molten aluminium [1,5]. However, PVD coatings are also prone to formation of cast alloy built-up layer (sticking) on their surfaces [3].…”
