Eds develops nanostructured ceramic powders capable of being customized for unique properties and structures.
Ceramic coating conductivity.
Most ceramic coatings are electrically nonconductive making them excellent insulators have a significantly higher level of abrasion resistance than most metals and are capable of maintaining their integrity under severely elevated temperatures sometimes up to 4 500 degrees fahrenheit.
250 000 700 000 psi at rt.
50 000 psi at rt.
80 000 psi at rt.
Insoluble in hcl and hf.
Low thermal conductivity ysz thermal barrier coatings.
Reacts with hot h2so4 and hno3.
The ceramic topcoat is typically composed of yttria stabilized zirconia ysz which is desirable for having very low conductivity while remaining stable at nominal operating temperatures typically seen in applications.
Conductive and non conductive coatings that generally incorporate such conductive fillers are used promote or limit the flow of heat or electrical current into or away from the object that is coated.
Low thermal conductivity thermal barrier coatings tbcs are preferred as they can increase turbine engine efficiency lower costs reduce emissions and increase durability.
