“…These results presented similar behaviour of other studies (Gündüz et al 2008, Korkut andGuller 2008) and confirmed the increase of quality of wood surface. According to Gündüz et al (2008), decrease of roughness is important for many applications of solid wood because can reduce the losses in planning machine and can increase the quality of wood surface.…”

This study aimed to characterise the effect of thermal treatment on physical and mechanical properties of açoita-cavalo (Luehea divaricata) wood. To achieve this, samples were treated at 160, 180 and 200°C for 2 h in an oven (dry conditions). Physical and mechanical characterisation was performed by weight loss, dry specific gravity at 12%, equilibrium moisture content, volumetric swelling and shrinkage, water absorption, water repellence, static bending and brittleness tests. Roughness and colour tests were performed in order to evaluate the modified surface. Main findings showed that dimensional stability of thermally modified wood increased, while mechanical strength of wood decreased as a function of temperature. A darkening of wood and a decrease in roughness were observed.

“…The average surface roughness value of panels treated at 225 � C for 30 min was 29% lower than control samples, followed by panels treated at 200 � C for 30 min (23% lower) and 175 � C for 15 min (10% lower). This was in agreement with the results of previous studies in solid wood and veneer sheets [12][13][14]21]. The R y and R z values of the panels also decreased with increasing heattreatment temperature.…”

A series of commercially manufactured medium density fiberboard (MDF) panels were exposed to a post-manufacture heat-treatment at various temperatures and durations using a hot press and just enough pressure to ensure firm contact between the panel and the press platens. Postmanufacture heat-treatment improved surface roughness of the exterior MDF panels. Panels treated at 225 � C for 30 min had the smoothest surface while the roughest surface was found for the control panels. Wettability and the adhesive bonding strength between veneer sheet and panel surface were decreased as post-treatment press temperature increased. A significant relationship (R 2 = 0 92) existed between contact angles and adhesive bond strength.

“…Boonstra et al (2007) reported that Brinell hardness parallel to the grain increased significantly (48%) and hardness perpendicular to the grain increased slightly (5%) for spruce. Korkut and Guller (2008) studied the effects of heat treatment on the physical properties and surface roughness of red-bud maple and concluded that surface roughness decreased with increasing temperature treatment and treatment times. (Korkut et al 2013) reported the effect of heat treatment on surface properties of wild cherry.…”

The objective of this study was to investigate the surface properties of a UV-system applied on laminated parquet made with untreated and heat treated wood (ThermoWood). In this study, wood specimens prepared from Scots pine (Pinus sylvestris) wood were heat treated according to ThermoWood method at 190 o C for 2 hours and at 212 o C for 1 and 2 hours adhesion strength, pendulum hardness, surface roughness, colour and glossiness were determined. The UV-system was applied in two different types according to manufacturer recommendations. Results show that lightness and glossiness decreases and red colour tone increases with heat treatment. Pendulum hardness increased initially, decreasing afterwards with the intensity of the heat treatment. Tests showed that adhesion generally decreased with heat treatment. No significant differences were found for the surface roughness although a slight decrease was observed.
