An Effectiveness Analysis for the Multi-Factor Accelerated Test of a Copper-Free Self-Polishing Antifouling Coating

Abstract

In order to eliminate or slow down the corrosion of various marine facilities, it has become a necessary choice to develop and use effective antifouling coatings for the development of marine equipment. This paper takes the newly developed copper-free, self-polishing, antifouling coating (CSAFC) as its research object, studies the performance changes in the exudation rate, adhesion, and abrasion rate by conducting a multi-factor accelerated test (MFAT) in the laboratory and a real sea test (RST), analyzes the correlation and acceleration multiplier in the two test environments, and provides a reference for the research on the relevant performance of this material. Firstly, it introduces the importance of antifouling coatings for modern maritime business, the importance of conducting accelerated tests in the laboratory, and explains the current test methods; secondly, it analyzes and fits the performance changes in materials such as the exudation rate, adhesion, and abrasion rate in different environments, and determines the main failure factors; finally, the correlation and acceleration multiplier are calculated using the Spearman rank correlation coefficient method (SRCCM) and acceleration factor method (AFM). The result shows that this MFAT has a good correlation and acceleration effect relative to the RST.
