The chromium oxide film has at least one partially polycrystalline portion and/or at least one amorphous portion depending upon the substrate(s) over which the chromium oxide film is formed. Partially polycrystalline portion(s) of the chromium oxide film are exposed, at room temperature, to an electron beam that has an accelerating voltage of at least 100 kilovolts to further crystallize the partially polycrystalline portion(s). Amorphous portion(s) of the chromium oxide film are exposed, at room temperature, to an electron beam that has an accelerating voltage of more than 100 kilovolts to crystallize the amorphous portion(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hardening chromium oxide films in a magnetic tape head and other structures","description":"A chromium oxide film is formed at room temperature.
