Surface densification is a process that can be used to increase the surface hardness of wood. One major drawback of the densification process is that the deformation from densification is often not permanent, and the wood can partly regain its original dimension upon contact with water.
Previous studies (Laine et al 2016) have found that a thermal modification post-treatment can reduce the set recovery in densified softwoods such as Scots pine, but this may also reduce surface hardness. Here, the effect of a thermal modification post-treatment on the set-recovery and surface hardness of a densified hardwood, i.e., Eucalyptus nitens (E. nitens) is investigated.
