Among such chemicals are e.g. ammonium sulphate and ammonium phosphate. The paper presents the experimentally established mechanical properties measured on the surface of fibrillated wood of Norway Spruce (Picea abies (L.) Karst.), and their comparison with values measured on undamaged wood. The results proved a loss of cohesion in the damaged surface layer accompanied with a decrease in tensile strength by up to 50% when compared to the values ascertained in undamaged wood. The impact of corrosion was also studied using hardness tests based on ball and pin indentation.
