阅读说明：本技术 用于制造触点部件的方法以及触点部件、真空开关管和开关设备 (Method for producing a contact element, and contact element, vacuum interrupter and switching device ) 是由 U.克鲁格 O.施蒂尔 于 2018-12-20 设计创作，主要内容包括：本发明涉及一种制造用于电气开关的触点部件(123、130)的方法,所述电气开关带有用于使电触点闭合的接触面(126)。所述触点部件至少部分由粉末制成,其中,为触点部件使用不同的粉末种类。根据本发明规定,为形成触点部件、例如接触层(130)而使用基于粉末床的增材制造方法、例如选择性激光熔化。接触层(130)由粉末床中的一组层制成,其中,为建立不同的材料组成而将例如由碳(C)制成的第一粉末种类的粉末与例如由银(Ag)制成的第二粉末种类的粉末以不同混合比例直接在层中混合。在此使用至少两个计量设备,利用所述计量设备将粉末种类直接在粉末床中混合。其具有的优点在于,能够利用仅两个粉末储备器形成不同的混合比例。能够制造具有浓度梯度的层或具有由不同材料制成的部分区域的层。还要求保护一种根据上述方法制造的触点部件、一种具有所述触点部件的真空开关管和一种具有所述真空开关管的开关设备。(The invention relates to a method for producing a contact element (123, 130) for an electrical switch having a contact surface (126) for closing an electrical contact. The contact parts are at least partly made of powder, wherein different powder types are used for the contact parts. According to the invention, a powder bed-based additive manufacturing method, for example selective laser melting, is used for forming a contact component, for example a contact layer (130). The contact layer (130) is made of a set of layers in a powder bed, wherein for establishing different material compositions, powder of a first powder species, for example made of carbon (C), is mixed directly in the layers with powder of a second powder species, for example made of silver (Ag), in different mixing ratios. At least two metering devices are used, with which the powder species are mixed directly in the powder bed. This has the advantage that different mixing ratios can be formed with only two powder reservoirs. It is possible to produce layers with a concentration gradient or layers with partial regions made of different materials. A contact element produced according to the above-described method, a vacuum interrupter having the contact element and a switching device having the vacuum interrupter are also claimed.)
