Abstract

一种用于从熔化物生产钛金属粉末的方法及装置。该装置包括具有内壁的雾化室，该内壁表面镀上工业纯钛或者完全由工业纯钛构成，以避免其中的钛金属粉末受到污染。在雾化室之后的流径中，该装置的所有部件的内表面也可表面镀上工业纯钛或者完全由工业纯钛构成。

Description

钛粉的生产装置及方法
技术领域
本发明涉及一种钛粉生产装置及方法，并且特别涉及一种能避免钛粉受到污染的装置及方法。
背景技术
在用于诸如航空航天之类关键应用的、由钛制成的零件的生产中，粉末冶金是一项重要的技术。在此生产工序中，钛金属粉末是基本原料。利用氩之类的惰性气体的雾化是用于生产具有高堆积密度的均匀的球状粉末的常用工艺。用于气体雾化的典型设备包括金属液流供给源（supply source）、雾化气体喷射以及冷却室。熔化钛的自由下落流与惰性气体喷射以高速碰撞，钛的雾化液滴在飞行穿过腔室时凝固，且聚集在腔室的底部。为了获得非常特定、受控的结构，需要使液滴凝固期间的冷却速率达到最高值。雾化室的设计和构造有几个重要方面：
1.腔室必须由不会与钛发生接触反应的材料构成；
2.腔室必须足够大，以便让钛液滴在接触到腔室壁或底部之前凝固；
3.腔室应容许完全疏散以避免气体污染；以及
4.腔室设计应便于检修，容许对其内部进行彻底清洁与检查。
不锈钢是用于构建钛雾化室的最常见的材料。此时一些钛液滴有可能在凝固之前碰撞到雾化室。这些液滴与不锈钢发生反应，生成性质上易碎的低熔点化合物。这些化合物成为污染物掺入钛粉流且在标准质量控制技术中不会被发现。由这些被污染的粉末制成的部件在使用中会造成严重故障。
发明内容
根据本发明，通过在雾化阶段之后，用不会污染生成的金属粉末的金属来衬套金属粉末流径或制造金属粉末流径，能消除粉末金属的污染。
至于钛金属粉末，雾化室壁优选地由CP-Ti即纯金属钛来衬套或制造。尽管当被生产的钛金属粉末是Ti-6A1-4V时，钛合金例如Ti-6A1-4V可被用于做衬套或腔室壁，但由于所有钛合金主要都由钛金属构成，CP-Ti是所有钛合金普遍接受的。
本方案适用于所有粉末金属生产系统，由于在腔室清洁工作中可引起金属污染，本方案尤其适用于从熔化物生产金属粉末，因为该方法使得偶尔出现的粉末团黏结到腔室壁。
从熔化物雾化包括气体雾化(GA)，其中金属的熔流被高速度的惰性气体喷射碰撞而形成粉末，还包括旋转电极法（PREP），其中金属棒快速旋转抛洒金属液滴时其末端熔化。
不论发生何种情况，通过电子束、等离子体焰炬、电弧、感应加热、激光加热或其它任何足够强力的加热方法，都可实现熔化。
附图说明
图1为本发明的用于生产钛粉的装置的部分示意图。
具体实施方式
参照图1，用于生产钛粉的装置10包括雾化或热喷室12，用于接收由诸如冷壁感应引导系统、电极感应熔化气体雾化工艺、等离子熔化感应引导气体雾化法、三重熔化法或其它任何已知系统等现有工艺供给的雾化的液态金属流。如图1所示，由雾化室12产生的粉末通过输送管道14、穿过旋风分离器16接着进入粉末容器18。
根据本发明，雾化室12的整个内表面20均镀有CP-Ti或者由CP-Ti构成，以避免从包括如前所述的钛粉末金属的熔化物生成的钛金属粉末受到污染。举个实例说明，雾化室12的内表面20上的CP-Ti镀层的厚度可为2mm。雾化室可由任何合适的材料构成，例如不锈钢。或者，雾化室12可由CP-Ti构成，而不是在由其它材料构成的内表面上镀CP-Ti。
为了进一步确保避免钛粉受到污染，在雾化室12之后的整个流径可在表面镀上CP-Ti或者由CP-Ti构成。例如，输送管道14、旋风分离器16以及粉末容器18可全部由CP-Ti构成或者均在内部镀上CP-Ti，以避免钛粉受到任何污染。
如果正在加工处理的钛金属粉末是Ti-6A1-4V，诸如Ti-6A1-4V之类的钛合金可被用于雾化室12中的内衬或腔室壁20及随后的流径（flow path），由于所有钛合金主要都由钛金属构成，CP-Ti是所有钛合金普遍接受的。
本发明结合目前考虑的最实用的优选实施例被描述出来，应理解本发明并不仅限于揭示出的实施例，而正相反，本发明涵盖了所附权利要求书的精神和范围内包括的各种修改和等同物。
