In contrast to the pure Al masteralloy, which led to the formation of Fe2Al5 coatings at 650 °C, a coating consisting of a thin Fe2Al5 outer layer and an FeAl inner layer was formed at 700 °C by utilizing a Cr 25Al masteralloy.
The four coatings were 1) a pure epoxy polymer coating, 2) a hybrid coating consisting of epoxy and silicone, 3) a ceramer coating consisting of organo-silicone and 4) a quasi-ceramic coating consisting of specialty silicone composition.
In order to explore the option of healing surface scratches in coatings using an expandable phase, the crack filling behavior of transparent, multi layer coating consisting of a polysiloxane film on top of a thin montmorillonite interlayer was studied.
A Bragg mirror coating, consisting of 36 alternating λ/4-layers of silicon dioxide (n = 1.45) and tantalum pentoxide (n = 2.04) was applied to the front of the chips.
There are demands to form nanolayered coating consisting of different materials in order to enhance the coating mechanical properties.
Based on the calculated results, a high strength Cu Ti intermetallic coating consisting of hard CuTi particles on a ductile Cu4Ti3 matrix is proposed.
