The influence of parameters on the evolution of the friction surfacing method - a review
Mehmet Erbil Özcan 대한기계학회 2022 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.36 No.2
Friction surfacing is a coating technology based on the accumulation of two metals with the same or different properties by transforming into a viscous structure without the need for an external heat source. The frictional surfacing process, which is based on the principle of coating by melting method by reaching the desired temperature with the contact of the consumable rod rotating around its axis, is used to bring the desired properties of the material together. The friction surfacing method, which can be made with many material pairs, requires a separate expertise in terms of achieving the desired temperature and adhesion of the materials to each other when made with the steel material pair. In this study, when the friction surfacing process is made with other materials and especially steel material combinations, the parameters used and the properties examined are investigated and the fundamentals of friction surfacing and recent developments are examined in the light of the literature. The advantages and disadvantages of the method, its usage areas and the theoretical and experimental studies for the people working on new coating methods have been brought together and a different perspective by examining the factors affecting the coating method one by one has been revealed with this study.

Electrochemical synthesis and corrosion behaviour of poly (pyrrole-co-o-anisidine-co-o-toluidine)
Süleyman Yalçınkaya,Tunç Tüken,Birgül Yazıcı,Mehmet Erbil 한국물리학회 2010 Current Applied Physics Vol.10 No.3
In this study, a ter-polymer film of pyrrole, o-anisidine and o-toluidine has been electrochemically synthesized on low carbon steel. The synthesis solution was aqueous oxalic acid containing 2:1:1 monomer feed ratio between pyrrole, o-anisidine and o-toluidine, respectively. The characterization of synthesized ter-polymer film was realized with help of UV–Vis absorption, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC) techniques. The stability of this ter-polymer film as a coating material has also been investigated on steel, in 3.5%NaCl solution. Under such severe conditions, the ter-polymer film was found to exhibit low permeability against water ingress. It was able to exhibit protective coating behavior on steel, even after 72 h exposure time. The DSC results revealed that the ter-polymer film had better thermal stability with respect to single polypyrrole film. The synthesized ter-polymer film was completely different in aspect of morphology,stability and other structural properties when compared to single polypyrrole film. This highly stable and extremely thin (0.80 ㎛) film can find application for various purposes (anticorrosive, electrocatalytic,etc.), at where the stability of polypyrrole like films constitutes a drawback.
