Tribochemical reactions of steel in cutting edge material during secondary wood products cutting

Abstract

In this paper, evidence of tribochemical reactions of a steel cutting edge during cutting of Secondary Wood Products (SWP) is reported. Applying Quantum Chemical (QC) methods, with semiempirical results verified using Density Functional Theory (DFT), it was determined that some thermal degradation products of the principle components of SWP would stabilize iron, from steel and iron from the binder in cemented carbide tool materials, in an oxidized state via octahedral hydroxy organometallic complexes. Evidence for the very complex thermal degradation processes of SWP components interaction with Fe corrosion processes is also observed in Thermal Gravimetry Analysis (TGA).
