Our Mission & Vision
IBC is an innovative surface engineering company that brings exceptional value to our customers and offers a great workplace for our employees.
Micro Arc Oxidation | CeraTough™
IBC’s PEO process (offered under the CeraTough™ trade name) uses a controlled high-voltage alternating current that is applied to a metal part submerged in an electrolytic bath. The high voltage and current causes an intense plasma to be created on the surface of the metallic component. This plasma oxidizes the surface of the part and grows a nano-structured ceramic oxide layer from the substrate material. The oxide layer diffuses into the material causing in subsurface oxidation. As a result, the process can produce very thick coatings of varying porosity. IBC has produced PEO coatings up to 250 microns thick on specific alloys, and ongoing research shows the feasibility of coating thicknesses of up to 500 microns.
