*Abstract

This invention provides a method for embedding a failure predicting mechanism within the working surface of die casting dies for molten metals. This is done using a piezoelectric thin film sensor that can be use with any coating system for the die. The sensor would detect the onset of failure in the protective layer by the sudden increase in stress level, which always accompanies such failure. The sensor can then facilitate precautionary measure to be adopted.
