Abstract: Determining a ″corrosion-lifetime″ for fasteners embedded in wood treated with recently adopted preservative systems depends upon successfully relating results of laboratory tests to inservice conditions. In contrast to laboratory tests where metal is embedded in wood at constant temperature and moisture content, the in-service temperature and moisture content of wood exhibit large fluctuations which affect the corrosion rate. The paper presents an approach for determining the corrosion lifetime of fasteners in which the calculated wood moisture content at the wood-fastener interface is used to predict the corrosion rate as a function of time through coupling two models. First, the moisture content across the wood component is calculated using a finite element code solving the coupled heat and mass transport equations with climatic data used as boundary conditions. Secondly, at the wood-fastener interface, the instantaneous corrosion rates are computed using an empirical corrosion model and integrated with time. Preliminary results for a simplified geometry are presented in this paper.
