| Summary: | Precursor‐based composite coatings were developed as barrier coatings on steel against oxidation and corrosion using a silazane in the system SiN as a polymer material and BN particles as a passive filler. After thermal treatment in air up to 800°C, dense and very well adhered ceramic composite SiNO/BN coatings with a thickness of 12 μm were achieved. These were investigated by means of scanning electron microscopy, energy‐dispersive spectrum, glow discharge optical emission spectroscopy, and adhesion measurements. Static oxidation tests on coated mild steel substrates up to 700°C displayed parabolic oxidation kinetics and a reduced weight gain by two orders in magnitude compared with uncoated substrates. |
