Publication: Plazma püskürtme yöntemiyle kaplanmış alüminyum silisyum poliester kaplamanın yapı ve özelliklerinin incelenmesi
Abstract
Plazma püskürtme yöntemiyle kaplanan plastik ve plastik esaslı kompozit kaplamalar endüstriyel amaçlı kullanılmaktadır. Söz konusu plastik ve plastik esaslı kompozit tozlar atmosferik şartlara, kimyasallara, çözücülere ve darbelere karşı dayanımlarının son derece yüksek olması bunlardan yapılan kaplamalara ilgiyi her geçen arttırmaktadır. Bu çalışmada plazma püskürtme yöntemi kullanılarak alüminyum silisyum esaslı poliester toz kaplamanın mikroyapıları, bağ mukavemetleri ve kaplama kalınlığındaki değişimlerin bağ mukavemetine (adhezyon) olan etkisi deneysel olarak incelenmistir. Deneysel olarak C 633-79 ASTM standardına uygun çekme testi ve aşınma deneyleri ise uygulanmıştır. Kaplamaların mikro yapıları tarama elektron mikroskobisi (SEM) ve ışık mikroskobisi ile saptanarak sonuçlar ortaya konmuştur.
Plastic powder coatings carried out by plasma spray technique are being used in industrial applications. Resistance of plastic and plastic based composite materials against chemicals, solvents, atmospheric conditions and high impact strength even at low servicetemperature increases importance of plastic powder coatings. In this study aluminium silicon based polyester coatings were carried out by plasma spraying. Microstructure and the effect of the coating thickness on the plastic bond strength and effect of the intermediate bond layer were observed at experimentally. The bond strength of the coatings were determined according to the ASTM C 633-79 Standard. Microstructural examinations of the coatings were examined by scanning electron microscopy (SEM) and light microscopy.
