An embodiment of the invention provides a method for manufacturing a eutectic ceramic particle reinforced titanium matrix composite, which comprises the following steps:
(1) To micron-sized Al 2 O 3 Powder and nanoscale ZrO 2 Powder mixing, wherein the Al 2 O 3 The powder accounts for 50wt% or more of the total amount of the mixed powder, and the balance is ZrO 2 A powder; in the present embodiment, however, the micro-scale Al 2 O 3 The particle size of the powder was 6. Mu.m, the ZrO 2 The particle size of the powder is 220nm; the Al is 2 O 3 Powder and ZrO 2 The mass ratio of the powder is 57.5wt%:41.5wt%.
(2) After the mixed powder is soaked in alcohol, the intermittent ball milling mode of stopping for 5-10min at the speed of 170-230rpm for 5-10min is adopted, the duration is 4-5h, and in the embodiment, the mass ratio of the ball milling balls to the materials is 4:1, ball milling at 200rpm for 4h in an intermittent ball milling mode of 5min and 5min stop each time, and drying at 80 ℃ for 24h to obtain eutectic ceramic powder, wherein argon is adopted for protection in the drying process.
Notably, the micrometer-sized Al 2 O 3 The melting point of the powder was 2313K, and the present invention particularly uses micron-sized Al with a powder ratio of (50 wt% to 60 wt%) 2 O 3 Powder and nanoscale ZrO 2 Powder, preferably 57.5wt%:41.5wt% of eutectic particle powder capable of mixing micro-sized Al under the condition of the ratio 2 O 3 The melting point of the powder was reduced from 2313K to 2133K, allowing for micron-sized Al 2 O 3 The powder is better melted, and the two oxide eutectic ceramic powders in the ratio can effectively inhibitCracking caused by the manufacturing process. The ball milling speed of the mixed powder in a roller is 170-230rpm, preferably 200rpm, the mixed powder is ball milled for 4-5h in an intermittent ball milling mode of stopping for 5-10min, preferably 4h in an intermittent ball milling mode of stopping for 5min, the drying temperature of the powder after ball milling is 75-85 ℃, preferably 80 ℃ to enable the powder to be dried and agglomerated after all moisture, and then the powder is filtered by a 100-mesh screen after simple grinding treatment to obtain the composite powder.
(3) The eutectic ceramic powder and the titanium alloy powder were ball-milled and mixed, in this example, the titanium alloy powder was Ti6Al4V, the eutectic ceramic powder was 3vol%, and the titanium alloy powder was 97vol%, specifically, 194ml of Tl6Al4V and 6ml of Al were contained in 200ml 2 O 3 -ZrO 2 The mass of 194ml of Ti6Al4V is about 501.72g,6ml of Al 2 O 3 -ZrO 2 The inventors have found that, when the content of the eutectic ceramic powder is increased, the molding effect of the mixed composite material is deteriorated, and the performance of the composite material is affected, and when the content is decreased, the hardness is not effectively ensured due to the low content, as the mass is about 6.36g, which is an average approximate value obtained by filling the powder into the measuring cylinder 3 times. The eutectic ceramic powder and the titanium alloy powder are subjected to uninterrupted ball milling for 24 hours at the revolution of 120rpm, then are dried for 4 hours at the temperature of 75-85 ℃, are filtered by a screen, and the particle size of the powder of the composite material is detected by a particle size analyzer, and the result shows that the eutectic ceramic particle reinforced titanium-based composite material with the particle size distribution of 20-45 mu m is obtained;
the 3D laser printing method of the eutectic ceramic particle reinforced titanium-based composite material belongs to laser selective melting printing, namely sending the dried eutectic ceramic particle reinforced titanium-based composite material into an SLM printer for laser 3D printing, specifically, setting up 30 rectangular blocks with different input parameters and sizes of 10mm multiplied by 12mm in a 125mm multiplied by 125mm substrate for parameter inspection printing. For 30 samples, the layer thicknesses (H) of samples No. 1-30 are 30 μm, wherein the sample scanning interval (D) of samples No. 1-15 is 0.12mm, and the scanning interval (D) of samples No. 16-30 is 0.1mm; the laser power (P) is increased from 150W at 50W power up to 350W; the scanning speed (V) increases from 600mm/s up to 1200mm/s in 300 mm/s; the laser power and the scanning speed increment are synchronously carried out; the scanning interval is 0.12mm; the layer thickness is 30 μm; the laser spot diameter was 70 μm. The prepared 3vol% eutectic ceramic composite material powder is subjected to laser 3D printing by adopting the set parameters, and the mixed powder contains eutectic ceramic particles, so that the first layer is set to be printed twice for improving the stability of the sample on the substrate, and finally the sample with the best forming effect is selected.
After printing, the normal temperature hardness of the selected sample is measured by using an iVicky V2.0 Vickers hardness tester, and the result shows that the laser power is 300W, the scanning speed is 900mm/s and the scanning interval is 0.12mm; the layer thickness is 30 μm; under the condition that the laser spot diameter is 70 mu m, the composite material powder has the best effect after 3D printing, and can reach 403.62MPa when the eutectic ceramic particle content is 3vol% at normal temperature and only reaches 330.94MPa when the eutectic ceramic particle content is 0 vol%; the high temperature hardness of the sample at 800 ℃ is measured by using an HTV-PHS30 high temperature Vickers hardness tester, and the result shows that the eutectic ceramic content at the high temperature is 291.55MPa when the eutectic ceramic content is 3vol% and 220.59MPa when the eutectic ceramic content is 0 vol%.
