Laser reactive cladding Cr7C3 ceramics enhancing iron base composite material according to embodiments of the present invention is detailed below, It is made by the preparation method for enhancing iron base composite material by the laser reactive cladding Cr7C3 ceramics described in above-described embodiment.
The composite material of the embodiment of the present invention makes Cr powder by the way that laser melting and coating technique is combined with situ synthesis techniques Chemical reaction in-situ preparation Cr7C3 ceramic enhancement phases are carried out with C powder, cladding layer, wherein cladding are formed in metal material surface Layer includes bottoming cladding layer and ceramic cladding layer, and the cladding layer appearance uniform is continuous and more smooth, and with high rigidity, wear-resisting The characteristics of.
Technical research personnel to enable this field are better understood from technical scheme of the present invention, with reference to embodiment The present invention is described in further detail.
Embodiment:
The basis material that the present embodiment is selected is Q235 steel, and cladding powder is Cr powder and C powder, according to chemical equation (1)
7Cr+3C→Cr7C3 (1)
By Cr powder and C powder in mass ratio 91:9 (atomic weight of Cr be 52, C 12, i.e., molar ratio be 7:3) proportioning mixing is carried out, And ground in spherical grinder uniformly, it is by the powder after ball milling after mixing, by the use of shellac solution as binding agent that its is pre- Matrix surface is applied to, preset coating thickness is about 1mm.
The present embodiment uses laser equipment as SLC -20 × 30D type digital control laser multifunctional processors, major technique ginseng Number:Machining area is X-axis 3000mm, Y-axis 2000mm, Z axis 600mm;Digital control system CNC models PMC-2000;Complete machine power consumption 100kVA;Mechanical dimensions 6500mm × 3500mm × 3500mm.Laser technical parameters are as follows:Laser power is 2500W, defocusing amount For 20mm, rectangular light spot size is 6mm × 1.5mm, sweep speed 1.0mm/s, 1.5mm/s, 2mm/s progress laser melting coating with Three kinds of cladding layers are obtained, by following experiments, the cladding layer under three kinds of different conditions is analyzed.
If Fig. 2 is the macro morphology of cladding layer under the conditions of different scanning speed.From (a) sweep speed 1.0mm/ of Fig. 2 S, (b) sweep speed 1.5mm/s and (c) sweep speed 2.0mm/s are different as it can be seen that under conditions of other technological parameters are certain Sweep speed, the cladding layer pattern that is obtained is different.Wherein when laser scanning speed is 1.5mm/s, clad layer surface is most To be smooth and smooth, and there is bright metallic luster, clad layer surface quality is preferable.When sweep speed is 1.0mm/s and V= During 2.0mm/s, clad layer surface is slightly coarse.Q235 steel surfaces laser melting coating Cr7C3 ceramic particle Fe radicle enhancings close as a result, Gold by sweep speed, can obtain that appearance is smooth, and the cladding layer of uniformly continuous.Preferably, laser scanning speed is During 1.5mm/s, the macro morphology of cladding layer is best.
Fig. 3 is the XRD diagram of Q235 steel surface Cr7C3 ceramic particle Fe radicle enhancing laser cladding layers under different scanning speed Spectrum.As seen from Figure 3, cladding layer is mainly by Cr7C3 and (Fe, Ni) phase composition.When sweep speed is 1.0mm/s, in cladding layer The diffraction maximum of Cr7C3 and (Fe, Ni) phase is presented, but diffraction maximum is weaker.When sweep speed is 1.5mm/s, in cladding layer The diffraction maximum of Cr7C3 and (Fe, Ni) phase is stronger.With the increase of sweep speed, as sweep speed 2.0mm/s, cladding layer XRD spectrum diffraction maximum weakens, this is because sweep speed is very fast, the molten bath lost of life, between the element in molten bath the reaction time contract It is short, the Cr7C3 ceramic enhancement phases of generation is caused to reduce.It follows that under the conditions of suitable sweep speed, laser reactive is utilized Melting and coating technique is reacted by the in-situ authigenic of Cr powder and C powder in Q235 steel surface laser synthesizing Cr7C3 ceramics cladding layers.
If Fig. 4 is Cr-C and Fe-C free energys and the graph of relation of temperature, Cr7C3 as shown in Figure 4 is ratio in molten bath The phase relatively stablized and be readily synthesized, and Fe3C is hardly produced or content is seldom.
Fig. 5 is the micro-hardness testing figure of cladding layer cross section, as shown in figure 5, being enhanced by above-mentioned Cr7C3 ceramic particles The microhardness analysis of iron based laser cladding layer cross section is it is found that cladding layer has higher hardness.
Fig. 6 is the curve graph of the friction coefficient wearing- in period variation of matrix and cladding coating, as shown in fig. 6, Cr7C3 The friction coefficient of ceramic particle Fe radicle enhancing laser melting coating layer surface is relatively stable in entire wear process, and cladding layer has very High wearability.
It follows that the laser reactive cladding Cr7C3 ceramics enhancing iron base composite material of the present invention has appearance smoothly, Clad layer surface even continuous and that there is bright metallic luster, and cladding layer has high, the wear-resisting characteristic of hardness.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art For, without departing from the principles of the present invention, several improvements and modifications can also be made, these improvements and modifications It should be regarded as protection scope of the present invention.
