In verschiedensten Projekten feilt man nun an der Verfeinerung der Messtechnik, um aus möglichst weiter Entfernung ausgesendete Signale untersuchen und so noch weiter in die Vergangenheit des Weltalls schauen zu können. Neben exzellenten Laser‐Interferometern, deren Funktionsweise hier kurz vorgestellt wird, braucht es zuverlässige Vakuumtechnik für den Erfolg dieser Messungen.Was beim Aufbau einer solchen Vakuumanlage zu berücksichtigen ist, und welche Pumpentypen dabei zum Einsatz kommen, wird hier anhand des Projekts „VATIGrav” beschrieben.","PeriodicalId":42842,"journal":{"name":"Vakuum in Forschung und Praxis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140790843","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This achievement is due to alloying of TiN with MgGd, which not only maintains the renowned wear resistance of TiN coatings, but potentially improves it through optimized deposition parameters.The key to the enhanced corrosion resistance lies in the addition of magnesium (Mg) and gadolinium (Gd). It reduces the coating's free corrosion potential, thereby mitigating the driving force for galvanic corrosion between coating and substrate. Moreover, at specific Mg to Gd ratios, a cathodic protection effect can be observed. Crucially, the presence of Gd is essential for this performance. It imparts hydrophobicity to the coating surface, reinforces a passivating layer and significantly enhances defect tolerance.This discovery paves the way for a sustainable alternative to electroplated chromium or combined electroplating and PVD, offering superior corrosion protection with minimal coating thickness.","PeriodicalId":42842,"journal":{"name":"Vakuum in Forschung und Praxis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140776879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Damit begründete er die Vakuumtechnik, deren weltweite Anwendung gegenwärtig rasant wächst. Das Guericke‐Vakuum ist der Druckbereich von Atmosphärendruck bis zu dem Vakuumdruck, den Otto von Guericke in seinen Experimenten minimal erreicht hat bzw. erreicht haben könnte. Der Vakuumdruck wurde von Guericke nicht gemessen. Aber mit seinen Versuchsbedingungen: 1. Wasser als Dichtungsflüssigkeit, 2. Glasrezipient und 3. Beobachtung von Wasserdampf beim Abpumpen, kann der unterste Vakuumenddruck anhand der Sättigungsdampfdruckkurve von Wasser rekonstruiert werden. Das Ergebnis ist abhängig von der Temperatur. Wie genau auch, das Guericke‐Vakuum entspricht dem Grobvakuum‐Bereich der Vakuumtechnik. In Würdigung Guerickes genialem Wirken zur Begründung und Entwicklung der Vakuumtechnik nennen wir das Grobvakuum auch Guericke‐Vakuum, welches den Druckbereich von Normaldruck bis 1 hPa umfasst.","PeriodicalId":42842,"journal":{"name":"Vakuum in Forschung und Praxis","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140788039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
