“…9 The wear resistance and wear pattern of the T1-melted cutting tool in peeling Beech was better than those of the T1-conventional peeling tool. 10 It could be summarized that the changes in microstructure and the increases in hardness due to laser melted as described above, which lead to the increase in the wear and corrosion resistances of the laser-melted steels, were attributed to the formation of a very fine microstructure, small proportion of retained austenite, and a higher precipitation of fine carbides within martensite.…”

Laser clad WC reinforced Ni-based intermetallic-matrix composites to improve cavitation erosion resistance Surface melting of Al-Cu-Mg alloy using a short-pulse, planar waveguide CO 2 laser for corrosion resistance improvement J. Laser Appl. 15, 233 (2003); 10.2351/1.1620005Laser cladding of cast aluminum-silicon alloys for improved dry sliding wear resistanceThe interest of high speed steel ͑HSS͒ for wood cutting tools remains very important because of their good tool edge accuracy and easy grinding. The main problem is their low resistance to both mechanical and chemical wearing. Resistance of HSS cutting tools to wearing is a primary concern in the applicability of the HSS cutting tools to a wood cutting operation. In order to increase their performance, a laser melting and cladding applied on the tool edges is presented in this paper. First, the annealed AISI M2 bar was melted, and the M2 powder was cladded onto the AISI L2 substrate by a laser beam. The microstructure and microhardness of the M2-clad and M2-melted were characterized. Second, their wear resistance was tested for cutting wood. The experimental results showed that the microstructures on the clad zone ͑CZ͒ of M2-clad and melted zone ͑MZ͒ of the M2-melted reveal fine and homogeneous iron dendritic structure, in which whole primary carbides were completely dissolved during laser cladding and melting. The energy dispersive spectroscopy ͑EDS͒ analysis indicated that the M2-clad reveals CZ microstructure with more uniform distribution of fine carbides compared to MZ microstructure. The M2-clad and M2-melted, which present almost the same microhardness, have larger microhardness compared to the M2-conventional. The results of wearing tests showed that the M2-clad and M2-melted cutting tools are better in wear resistance, edge roughness, and suffer less edge fractures than the M2-conventional peeling tool. Laser melting and cladding are considered to be valuable techniques to improve the performance of the M2 high speed steel cutting tools for wood machining application.

“…This process has been investigated by different authors by use of high power lasers. CO 2 or Nd:YAG lasers have been the most used [12][13][14]. The rapid melting of the surface layer induced by irradiating with a laser beam, and its rapid solidification in contact with the cold substrate, are the main characteristics of this treatment.…”

Industrial applications require parts of components with specific surface properties such are good corrosion resistance, wear resistance and hardness. Alloys with those properties are usually very expensive and there is a great interest in reducing the cost of components for fulfilling these requirements. In this sense, laser surface processing has been used as a cost-effective technique to improve the surface properties of materials, by use of the laser beam heat for modification of its structure and physical characteristics. Laser surface treatments can be divided into direct processes, which only need the generated heat, such are hardening and melting, and processes which need filler material as alloying and cladding. Therefore, the aim of this paper is to summarize the results of several works based on laser surface treatments, in particular, hardening and melting of hot and cold work steels, and laser cladding of forming tools with nanoparticles. The microstructural characterization and mechanical properties (microhardness, wear resistance) will be described in each case.
