Resumen En este trabajo se estudió el comportamiento a la corrosión y la adhesión de dos recubrimientos DLC ("Diamond Like Carbon"), "Soft" y "Hard", depositados por PACVD ("Plasma Assisted Chemical Vapour Deposition") sobre acero AISI 420, templado y revenido y/o nitrurado por plasma. Se analizaron por espectroscopía Raman y midió dureza en superficie. Se observó la microestructura por OM y SEM. Se realizaron pruebas de adhesión con indentación Rockwell C. Se practicaron ensayos de Niebla Salina e inmersión en HCl. Los DLC "Soft" presentaron una dureza de 500 HV y un espesor de 20 µm, mientras que los "Hard" tuvieron 1400 HV y 2,5 µm. Ambos recubrimientos presentaron bajo coeficiente de fricción y buena adhesión sobre el sustrato nitrurado...
