项目摘要

A fabrication method of a metallic closed cellular material containing ceramics has been developed.1)A fabrication method of a metallic closed cellular material containing ceramics by Spark Plasma Sintering (SPS) Method.Ceramics particles were coated with nickel-phosphorus alloy layer using electro-less plating were filled into the graphite die and sintered by a spark plasma sintering method. Then metallic closed cellular materials containing ceramics were fabricated.2)A fabrication method of a metallic closed cellular material containing ceramics using porous ceramics particles coated with nickel-phosphorusPorous ceramics particles coated with nickel-phosphorus alloy layer using electro-less plating were pressed into pellets (green pellets) and sintered at high temperatures in a vacuum condition. These particles were also sintered by a spark plasma sintering method. Metallic closed cellular materials containing ceramics were then fabricated by both methods.3)Evaluation of closed cellular materialsThe compressive tests and the three points bending tests were carried out to measure the mechanical properties of these materials. The compressive test results showed that these metallic closed cellular materials were brittle and do not have long plateau region. The results of three points bending tests showed that the specimens which have different thickness of cell wall and include different materials have different maximum tensile strengths.4)Fabrication of small devicesUsing graphite dies and punches, 10x20mm specimen of metallic closed cellular materials containing ceramics with the thickness of 1-3mm could be fabricated by spark plasma sintering method.

本发明涉及一种含陶瓷的金属闭孔材料的制造方法。1）放电等离子烧结（SPS）法制造含陶瓷的金属闭孔材料的方法，在陶瓷颗粒上用化学镀法镀上镍磷合金层，填充到石墨模具中，用放电等离子烧结法进行烧结。2）使用涂覆有镍-磷的多孔陶瓷颗粒的包含陶瓷的金属闭孔材料的制造方法将使用化学镀涂覆有镍-磷合金层的多孔陶瓷颗粒压制成丸粒（绿色丸粒）并在真空条件下在高温下烧结。这些颗粒也通过放电等离子体烧结法烧结。采用两种方法制备了含陶瓷的金属闭孔材料。3）闭孔材料的评价通过压缩试验和三点弯曲试验，测试了材料的力学性能。压缩试验结果表明，这些金属闭孔材料是脆性的，没有长的平台区。三点弯曲试验结果表明，不同孔壁厚度和不同材料的试样具有不同的最大抗拉强度。4）小型器件的制备采用石墨模具和冲头，利用放电等离子烧结法可以制备10 × 20 mm的含陶瓷的金属闭孔材料试样，试样厚度为1- 3 mm。
