For many wood machining processes, the interest of tool steels remains very important because of their good tool edge accuracy and easy grinding. The main problem is their low resistance to wearing and moderately toughness. To increase their performance, a laser treatment applied on the tool edges was presented in this paper. First, the surface of AISI-T1 samples was scanned by a laser beam with varying laser treatment conditions (laser power and scanning speed). Second, an investigated laser treatment condition promising good characteristics (high hardness, high melt volume, no cracks) was chosen and applied on T1 peeling tool edges, then its wear resistance was tested for peeling beech wood. The experimental results show that the microhardness of the melted T1 samples was affected by the laser power and the scanning speed. The microhardness was slightly increased with increasing laser power and with decreasing scanning speed. The microhardness of the melted T1 samples under each treatment conditions after three times one hour each tempering at 550uC was higher than that of the conventionally hardened T1. The melt volume of the laser treated T1 samples was also increased with increasing laser power and with decreasing scanning speed. The laser treatment condition with a laser power of 3000 W and a scanning speed of 200 mm min 21 was considered to provide good characteristics and was applied for melting the edge of T1 peeling tool. The wear resistance and wear pattern of the melted T1 peeling tool in peeling beech was better than those of the conventionally hardened T1 peeling tool. 4 Images (SEM) of microstructures of a unmelted T1, b, d, f MZ and c, e TZa at power of 3000 W and at scanning speed of 200 mm min 21 , MZ and Tza without tempering Darmawan et al.

“…[3][4][5][6][7] However, studies on the synthesis of wear-resistant thin film by plasma polymerization are few compared with plasma treatment to enhance surface adhesion. The most popular methods for synthesis of ultrahardness or wear-resistant thin film is chemical vapor deposition, 8,9 but its high reactive temperature (greater than 900 -1000°C) and its relative low deposition rate have limited its uses in field of polymer. The process of plasma polymerized thin film deposition could [5][6][7] greatly lower the reactive temperature with a higher deposition rate and obtain one kind of even and better bonded thin film.…”

Plasma-polymerized deposition of an acetylene-hydrogen-silane mixture (C 2 H 2 -H 2 -SiH 4 ) to obtain thin film with good wear behavior on a high-density polyethylene (HDPE) surface was present in this work. It was found that the bond between thin film and HDPE substrate was excellent and H 2 gas in system led the deposited thin film to better adhesive properties, but slower thin film deposition rate. Surface wearresistant properties of modified HDPE were improved with the input of SiH 4 . Infrared and X-ray photoelectron spectroscopy spectra suggested that there be large quantities of ϾCAO, OOH, COSi, and SiOO groups in thin film and that the ratio of C to Si was increased due to the addition of SiH 4 and H 2 , which inferred that the thin film structure and components lie between organic and inorganic materials.
