“…Coatings of these materials can be successfully prepared by laser particle injection [1][2][3] and laser cladding [4][5][6]. In the first technique powders of reinforcement material are injected into the melt pool generated in a metallic alloy substrate by a laser beam [1], while in the second mixtures of ceramic and metallic powders are used to create an overlay layer of the MMC [5].…”

“…Ayers and co-workers [1][2][3] injected 30-50 vol.% of 100 m size TiC into laser treated titanium alloys and observed a hardness level of about 450 Hv, the hardness being measured between the embedded particles. This was an increase of over 100% of the hardness of the base alloy.…”

The formation of composite layers using a 2.8 kW laser beam of 186 and 373 MJ m −2 energy densities, on commercial purity titanium surfaces preplaced with 3 m size, 1-4 vol.% SiC p powder in a 100% nitrogen environment, produced gold colour tracks. The tracks gave reflective surfaces after glazing at an energy density of 373 MJ m −2 and dull or a mixture of dull and shiny surfaces at 186 MJ m −2 energy density. Surface cracks were visible in tracks containing 1 and 2 vol.% SiC p , but none were observed in the 4 vol.% SiC p tracks glazed at both energy densities. In the track cross sections, vertical cracks were seen in the 373 MJ m −2 tracks but it was absent in 186 MJm −2 tracks. The SiC p particles completely dissolved in all the tracks processed in this investigation producing a complex and inhomogeneous microstructure of dendrites and needle particles. At the half way of the melt depth from the surface, the dendrites were larger and densely populated, especially after glazing at 373 MJ m −2 . The hardness measurement of the MMC layer recorded a wide range of hardness values which gave loops in the hardness profiles. Hardness values ranging from 700 to 1000 Hv were observed up to a melt depth of 1 mm in many tracks and the maximum surface hardness of 2250 Hv was measured in the track containing 1 vol.% SiC p and glazed at 373 MJ m −2 . The surface hardness developed 5.6-15 times the base hardness (150 Hv) depending on the dendrite population. The 3 m size SiC p produced MMC layers 1.5-2 times greater than those previously observed with 6 m SiC p . The large surface area for an equivalent volume fraction of the three micron carbide particles is considered to have a high laser coupling action and hence absorbed more heat energy to produce deeper melt depth compared to those produced using the 6 m SiC p .

“…During LMI hard particles with the size range of 10-100 µm are blown by a gas stream into a liquid metallic pool, melted by a fast moving laser beam. The particles are usually carbides [1,[8][9][10][11][12]14,[18][19][20][21][23][24][25][26][27][29][30][31][32][33][34][35][36][38][39][40][41][42][43], borides [3][4][5][6][7], nitrides [2], oxides [13,15]), or even soft Pb droplets [28].…”

“…Laser Melt Injection (LMI) technology has been known since the 1980s [1] and has been used to improve surface characteristics of metallic alloys, such as steels [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17], aluminum [18][19][20][21][22][23][24][25][26][27][28], titanium [27,[29][30][31][32][33][34][35][36][37][38][39], nickel [40][41][42] and magnesium [43]. During LMI hard particles with the size range of 10-100 µm are blown by a gas stream into a liquid metallic pool, melted by a fast moving laser beam.…”
