T1 - Corrosion and abrasion resistant protective coatings for biomass combustion N2 - The environmental concerns about availability of fossil fuels and greenhouse gas effect increase and alternative renewable fuels for power plants are gaining significantly of importance. One of the alternative renewable fuels is biomass but it is a difficult fuel because of its diversity and complexity. It can contain high percentages of K and Cl responsible for corrosion together with sand that have additionally an abrasive effect during combustion. Because of permanently extending the surface reaction due to abrasion the corrosion of the materials increases. In particular in power plants, the superheater tubes are exposed to a corrosive abrasive attack that is one of the main sources of concern. The development of new alloys for multilayer surface, which combines corrosive and abrasive resistance is therefore of high importance. Those new technical approaches must be at the same time cost-effective to be an alternative to conventional materials. This paper presents the principle of experimental methods developed for the investigations of high temperature corrosion combined with abrasion in thermochemical processes with high hydrochloric acid concentrations like during biomass combustion. The aim of the presented investigation methods it to test and develop suitable alloys for coatings for the super heater tubes of biomass power plants. First results of abrasion investigations show improved abrasion resistance compared to the multi-component reference material Alloy 625.
