Electromechanical devices and methods for forming coating layers on components thereof

A method comprising:

• forming an intermediate coating product from a ceramic powder for application of the ceramic powder, wherein the ceramic powder includes:
• between 47 and 64 weight percent B2O3;
• between 5 and 7 weight percent SiO2;
• between 9 and 14 weight percent ZnO;
• between 6 and 9 weight percent BaO;
• and
• between 16 and 22 weight percent Bi2O3;
• applying the intermediate coating product to a surface of a component of an electromechanical device;
• and
• thermally processing the intermediate coating product at a temperature of 800° C. or less to melt the intermediate coating product and thereby form an electrically insulative coating layer on the surface of the component, wherein the coating layer is configured to function in operating environments having temperatures in excess of 180° C. for at least for 40,000 operating hours of the component.

An electromechanical device, comprising:

• components each having one or more surfaces formed of one or more metallic materials and susceptible to operating environments having temperatures in excess of 150° C. for a long term;
• and
• electrically insulative coating layers formed on the one or more surfaces of the components, wherein the coating layers are configured to function in operating environments having temperatures in excess of 180° C. for at least for 40,000 operating hours of the components;
• wherein the coating layers include:
• between 27 and 33 weight percent B2O3;
• between 24 and 30 weight percent BaO;
• between 12 and 16 weight percent MgO;
• between 11 and 13 weight percent SiO2;
• between 5 and 7 weight percent Al2O3;
• between 3 and 4 weight percent ZrO2;
• and
• between 2.5 to 3.5 weight percent TiO2.
