What is PVD Coatings for Die-Casting Durability about?

This document summarizes a study on using PVD coatings and different die materials to extend the life of die-casting dies. It tested three H series and two maraging hot work tool steels with and without TiN, TiAlN, and CrN PVD coatings. The coatings provided significant corrosion and erosion resistance from molten aluminum but influenced heat checking resistance depending on the substrate material and coating variables. Of the steels tested, only H19 steel had a significant reduction in heat checking resist
