利用外场作用可以改善原位合成反应的热力学与动力学条件,起到促进原位反应进行的 作用, 同时, 外场作用可以控制颗粒相的过分长大或偏聚团簇现象, 因此, 在外场下原位 合成金属基复合材料越来越受到研究者的重视。中国专利: CN 1676641A (公开日:2005.10.5, 发明名称: 制备金属基纳米复合材料的磁化学反应原位合成方法)提出在磁场 (稳恒磁场、 交变磁场和脉冲磁场) 下进行原位磁化学反应合成, 该专利介绍的方法在细化增强颗粒方 面具有非常好的效果。 中国专利: CN 1958816 (公开日: 2007.05.09, 发明名称: 功率超声 法制备内生颗粒增强铝基表面复合材料工艺) 提出利用功率超声制备内生颗粒增强 (Al3Ti 相)铝基表面复合材料, 使增强相在基体的表层分布均匀, 界面结合更好。
但是,单一施加电磁场或超声场对原位反应合成颗粒增强金属基复合材料的作用仍不能 令人满意。 施加单一电磁场时, 由于电磁场在金属熔体内存在难以克服的集肤效应, 磁场 在金属内的作用强度按指数规律衰减, 因此电磁场对熔体的有效作用深度有限, 特别对于 大体积的熔池或采用较高频率的电磁场时, 熔体内电磁场作用的差异非常明显, 即电磁场 在熔体内作用出现严重的不均匀性, 中心区域电磁场作用微弱而边缘区域电磁场作用很强。 单一施加超声场时, 由于超声波是一种机械疏密震荡波, 属于纵波, 其作用有很显著的方 向性, 同时超声波在金属熔体中的衰减亦十分严重, 因此, 超声效应主要集中在变幅杆下
低频交变磁场的电磁参数范围, 频率: 0.1Hz〜60Hz, 工作电流: 1A〜10000A, 根据熔 体量、 种类和搅拌强度调节电磁参数, 对铝、 铜基熔体, 可采用较高频率, 对铁基、 镍基、. 锌基熔体, 采用较低频率。
超声场的频率 10kHz〜30kHz, 超声强度 0.5kW/m2〜60 kW/m2。
具体步骤为: 金属基熔体精炼后调整到反应起始温度, 加入能与金属熔体原位反应生成 颗粒相的反应物粉剂, 开启磁场搅拌稳定后, 插入超声变幅杆到液面下 5〜6mm, 接通超声 装置, 超声处理时间 60s〜600s, 时间到后, 停止超声设备, 关掉磁场, 静置到浇注温度后 进行浇注。
补充说明: 低频交变磁场也可采用上述参数范围内的旋转搅拌磁场或行波搅拌磁场, 旋 转搅拌磁场施加在熔池的侧面, 或行波磁场施加在熔池的底部, 均属本发明提出的方案。

为弥补单一施加电磁场或超声场的不足,本发明提出采用电磁场与超声场耦合作用下原 位合成颗粒增强金属基复合材料的新方法。 发明内容
本发明的目的是:提供一种在电磁场与超声场耦合作用下熔体反应合成制备内生颗粒增 强金属基复合材料的新方法, 制备高性能原位颗粒增强金属基复合材料。
本发明的基本原理是:在原位颗粒增强金属基复合材料的反应合成过程同时施加磁场和 高能超声场, 利用磁场对熔体产生电磁力、 磁化及涡流感应热等磁化学原理和高能超声场 在熔体内产生的声空化和声流冲击等声化学原理对复合材料合成制备过程进行耦合作用, 达到控制颗粒相的分布、 抑制颗粒长大和团簇并改变原位合成反应的热力学和动力学条件 的目的, 实现磁场磁化学和高能超声场的声化学耦合作用下合成颗粒增强金属基复合材料。 该新方法的原理结合图 1实现本方案的装置示意图说明如下:
在保温耐火材料制成的熔池(或坩埚) 1内合成制备复合材料熔体 2, 在熔池(或坩埚) 上部插入高能超声变幅杆 3, 对熔体施加超声处理, 在熔池 (或坩埚) 外侧施加磁场 4。 根 据复合材料熔体制备方法以及要求效果的不同, 可以选择不同的磁场施加形式。 因此外加 磁场 4可以是强脉冲磁场、 高频振荡磁场及低频旋转磁场三种磁场。
磁场与超声场耦合作用的原理是:
( 1 ) 外加磁场 4选用.强脉冲磁场, 即强脉冲磁场与超声场稱合作用, 强脉冲磁场在熔 体内的脉冲电磁力、 脉冲磁化力和感应电流的焦耳热, 均对原位化学反应有加速作用, 并 能起到使颗粒相弥散分布的目的, 但脉冲磁场在金属熔体内有一定衰减, 熔体边缘区域的 反应受磁场的影响强而中心部位较弱, 因此要选择与高能超声耦合作用, 功率超声通过在 熔体内的空化效应和声流冲击, 空化效应使颗粒团簇得到控制, 声流冲击起到微区搅拌作 用, 由于超声场作用区域是中心区域强而边缘弱, 两者正好互相弥补不足, 耦合作用达到 加速原位反应, 使颗粒相快速生成并呈弥散分布的目的。
(2) 外加磁场 4也可选用高频振荡磁场, 高频振荡磁场由于在熔体内存在集肤效应, 所以集中作用于熔池的边缘, 对复合材料熔体中的颗粒形成振荡的电磁力, 使颗粒团簇得 到控制, 超声场仍主要作用于熔池中部区域。
(3 ) 当对复合材料的颗粒大小及分布要求稍低时, 磁场 4也可以选择采用低频搅拌磁 场与功率超声耦合作用。 特别是当处理的金属量大到以吨位计量时, 由于目前高频振荡磁 场和强脉冲磁场设备的限制, 采用较强的低频搅拌磁场和高能超声耦合作用, 也能达到较
理想的效果。 其原理是: 高能超声通过在熔体内的空化效应和声流冲击, 空化效应使颗粒 团簇得到控制, 声流冲击起到微区搅拌作用, 外加的低频搅拌磁场 4对使整个熔池电磁搅 拌, 超声处理效果更加明显, 且超声处理的局部效应或集中效应得以控制。
基于上述原理, 实现本发明的技术方案是:

该方法特别适用于制备金属基复合材料量少但要求性能极高的复合材料。
(2) 高频振荡磁场与高能超声耦合作用
高频振荡磁场的电磁参数范围为: 高频基准波频率 10 kHz〜30kHz, 调幅振荡波频率为 1Ηζ〜30Ηζ, 功率范围 0〜100kW, 根据熔体量、 种类、 熔池和搅拌强度调节电磁参数, 对 铝、 铜基熔体, 可采用较高基准波频率, 对铁基、 镍基、 锌基熔体, 采用较低基准波频率, 振荡波频率根据熔体搅动情况确定, 与反应器的结构和金属熔体的种类有关, 以熔体不出 现强烈紊流为宜。
超声场的频率 10kHz〜30kHz, 超声强度 0.5kW/m2〜60 kW/m2。
具体步骤为: 金属熔体精炼后调整到反应起始温度, 加入能与金属熔体原位反应生成颗 粒相的反应物粉剂, 幵启磁场稳定后 ·, 插入超声变幅杆到液面下 5〜6mm, 接通超声装置, 超声处理时间 60s〜600s, 时间到后, 停止超声设备, 关掉磁场, 静置到浇注温度后进行浇 注。
