Luminescence method − Instrument used for detection of surface cleanliness

Abstract

The process of surface treatment has a significant role in several industrial applications. Among the processes that most affect the quality of surface treatment are mainly the pre-treatment processes aimed at cleaning the processed surfaces. Degreasing of the treated surfaces has in this technological phase an important role. The article is devoted to quality control after surface pre-treatment. It deals with modern method for detecting grease-based surface contamination by the luminescence method. Impurities such as grease, oil and others have characteristic luminescence after illumination by UV light source. This principle can be used to determine the cleanliness of the part’s surface thereby ensuring the quality of the observed surface. Surface cleanliness is a very important factor for the correct application of subsequent technological processes.
