Cracks and pits in a surface can be spotted with the help of fluorescent dye and ultraviolet (UV) light in a process called liquid penetrant inspection. Anotek has extensive experience with comparable audits. We perform liquid penetrant testing in accordance with NAS410 and ASTM E1417. Additionally, we are Nadcap and BAC5423 certified. It is now normal practice to use a technique known variously as “Chem film,” “Gold Alodine,” or “hexavalent chromate” instead of the older method of anodizing. Given the specialized nature of the process, we recommend scheduling an appointment to discuss your needs and confirm that moving forward is the best course of action. Anotek meets the requirements of both MIL-DTL-5541 and BAC5719.
