Characterisation of Reinforced BTSE Films Deposited on Anodized Aluminium Substrate

This paper discusses the improvements achieved in the anticorrosive properties of some silane films by pretreating the metallic substrate prior to films deposition and by reinforcement with some reinforcement agents. One has compared the behaviour of silane films, deposited on aluminium substrate, and the reinforced silane films deposited on anodised aluminium substrate. The use of scanning electron microscopy highlighted the modifications of substrate surface characteristics prior and after the anodisation process, while electrochemical techniques such as open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarization were employed in order to characterize the deposited films from the corrosion behaviour point of view.

MODIFICATION OF THE T-17 TESTER HOLDER TO ENABLE TRIBOLOGICAL TESTS TO BE CARRIED OUT IN A ROLLER-PLATE COUPLE

The aim of this paper is to propose a solution that will make it possible to perform tribological tests of materials intended for rolling elements (e.g., rollers) interacting with a flat surface (e.g., sliding door guide). Tribological tests were carried out on a T-17 test stand, which was equipped with a holder that made it possible to perform tests in the roller-plate couple. The paper presents the results of tribological tests of a typical polymer PA 6 used in sliding door systems interacting with anodised and non-anodised aluminium alloys. The analysis of the tribological tests was supplemented by stereometric studies. The studies showed the possibility of performing tests for the roller-plate couple with the use of a T-17 test stand. The influence of the modification of the aluminium alloy surface (material of the sliding door guide) on tribological properties of the examined friction node was also shown.
