3the intermetallic compound such as Al and TiAl, as shown in Fig. 1 a to Fig. 1 e.In laser cladding process, the laser beam of high-energy-density acts on specimen surface, makes fore-put powder and surface layer fusing, forms small molten bath, and reaction in－situ occurs in molten bath, generates above-mentioned strengthening compound.
In laser cladding process, as metallographic phase, Al and Ti partial reaction generate intermetallic compound strengthening phase, and Ti and Si reaction generate hard ceramic phase, are distributed in the substrate of metal formation, form and the similar composite structure of concrete.The good plasticity and toughness of the high rigidity of ceramic phase and metallographic phase match, and can significantly improve the performance of cladding layer.
As shown in Figure 2, cladding layer cross-sectional structure pattern, molten bath is the crescent shape of the thin thick middle in both sides, coating pore-free and crackle, coatings and substrate is metallurgical binding, junction smoother.As the tissue topography of each sample crucible zone of Fig. 3 a to Fig. 3 e cladding material powder preparation that is different proportionings, as shown in Figure 3 a, weave construction is dentrite and some irregular bulk crystals, weave construction is short and small dendrite and some irregular block crystalline substances as shown in Figure 3 b, weave construction is as shown in Figure 3 c uniform gritty texture, and the structure organization shown in Fig. 3 d, Fig. 3 e is flat crystal.Along with the increase of the mass percent of Si in powder mixture ratio, weave construction is refinement gradually, when the quality percentage composition of Si reaches 15%, organize the most tiny evenly, when the content of Si further increases, structure starts coarsening.For the tissue of further optimizing structure, when content one timing of Si powder, when the mass percent of Ti powder reaches 50%, structure is the most tiny.
The microhardness of the cladding coating of the cladding material powder preparation of different proportionings, under 0.2kg load, tests under the condition of loading time 10s as shown in Figure 4.As seen from the figure, the microhardness of each sample is apparently higher than the microhardness of titanium alloy substrate.The microhardness of 50Ti-35Al-15Si cladding coating is the highest, and maximum can reach 1230HV
0.2, be about Ti-6Al-4V matrix hardness (320-360HV
0.2) 3.5 times, the about 0.9mm of cladding layer thickness, is the zone of transition between cladding layer and matrix apart from the region of cladding layer 0.9-1.1mm, apart from cladding surface, surpass 1.1mm after microhardness significantly reduce.The microhardness of 50Ti-40Al-10Si cladding coating is minimum, and microhardness scope is at 782-950HV
0.2, being about the 2-3 of Ti-6Al-4V matrix hardness doubly, cladding layer thickness is about 0.7mm, apart from cladding surface, over microhardness after 0.7mm, significantly reduces.The microhardness scope of 40Ti-35Al-15Si cladding layer is 897-1168 HV
0.2, the about 0.9mm of cladding layer thickness, significantly reduces over microhardness after 0.9mm apart from cladding surface.The durometer level of 60Ti-25Al-15Si and 50Ti-30Al-20Si is more approaching, apart from the region of cladding layer 0.8～1.0mm, is the zone of transition between cladding layer and matrix, increases hardness drop to gradually matrix hardness with distance.Because coated powder proportioning is different, the microhardness of laser cladding layer is not identical yet, and along with the increase of Si powder content, the microhardness of cladding layer increases, the Ti producing in cladding layer
5si

2ceramic phase increases.But when Si content surpasses 15%, the microhardness value of cladding layer reduces, because Si powder content increases, the tissue change in coating causes greatly lower hardness.
As shown in Figure 5, the abrasion loss of laser cladding layer, when added load is 10kg, the time, while being 10min, the wear weight loss amount of laser cladding layer was all starkly lower than the wear weight loss amount of titanium alloy substrate.The average abrasion amount of every ten minutes of 40Ti-45Al-15Si cladding layer is that 0.0170g is 1/3 of titanium alloy substrate average abrasion amount 0.0514g.The average abrasion amount of 50Ti-35Al-15Si cladding layer is that 0.0152g is 1/3.5 of titanium alloy substrate average abrasion amount.The average abrasion amount of 60Ti-25Al-15Si cladding layer is that 0.0186g is 1/2.8 of titanium alloy substrate average abrasion amount.Explanation by Laser Cladding Treatment after the wear resistance of alloy surface with respect to matrix, be significantly improved.The wear resistance of 50Ti-35Al-15Si cladding layer is best, and because the microhardness of 50Ti-35Al-15Si cladding layer is the highest, the homogeneous microstructure of its cladding layer is tiny, good toughness.
