Abstract

Effect of Heat Treatment of Wild Cherry Wood on Abrasion Resistance and Withdrawal Capacity of Screws

Highlights

  • The results indicated that there was a greater reduction in withdrawal capacity of screws (WCS) for thermal modification conditions, and they concluded that deformation increased at higher temperatures based on the analysis of the images of the deformed surface left by the screws

  • Depending on the results found in the loops of 0-250 and [250-500] in thickness reduction (TR) and weight loss (WL) for abrasion resistance (AR), the effects of aging of the abrasive material were assessed

  • The maximum WL occurred in UT, whereas the minimum WL occurred in the variation of HT4; WL in the HT4 samples was about 30 % less than in the UT samples

Summary

Introduction

Wooden material has certain undesirable features, such as the change of dimensional stability, biological degradation, and color change, but wooden materials are still used extensively in many products. These adverse features reduce the lifetime and value of wooden material. ThermoWood is one of the heat treatment methods developed in the 1990s by VTT Technical Research Centre of Finland. In this method, wooden material is heated at a minimum of 190 °C in steam. The bending resistance of the wooden material decreases (Anonymous, 2003)
