Description
Kühlflüssigkeit für aus Magnesiumlegierungen bestehende Teile von Brennkraftmaschinen In neuerer Zeit ist vielfach und mit gutem Erfolge empfohlen worden, dem als Kühlmittel für Brennkraftmaschinen verwendeten Wasser zwecks Erhöhung der Kühlwirkung und Verminderung der Einfriergefahr in der kalten Jahreszeit entweder mehrwertige Alkohole, wie z. B. Glykol und Glycerin, zuzu-#,etzen oder aber diese Stoffe selbst überhaupt als Kühlmittel zu verwenden. Dabei hat sich bezeigt, daß bei Verwendung von Magnesium und seinen Legierungen als Baustoff für die von der Flüssigkeit durchflossenen Teile das .Metall von mehrwertigen Alkoholen teils schon bei gewöhnlicher Temperatur, regelmäßig aber bei den in den Motoren (z. B. in dem Zylinderblock) auftretenden höheren Temperaturen in mehr oder minder großem Umfange angegriffen wird.Coolant for magnesium alloy parts of Internal combustion engines In recent times is recommended many times and with good results been, the water used as a coolant for internal combustion engines for the purpose of increasing the cooling effect and reducing the risk of freezing in the cold season either polyhydric alcohols, such as. B. Glycol and Glycerin, zuzu - #, et or these To use substances themselves as coolants at all. It has been shown that when using magnesium and its alloys as a building material for the Liquid flowed through parts of the metal of polyhydric alcohols partly already at normal temperature, but regularly at the temperatures in the engines (e.g. in the Cylinder block) occurring higher temperatures to a greater or lesser extent is attacked.
Es wurde nun die Beobachtung gemacht. daß durch einen geringen Zusatz
von Alkalifluoriden zu den als Kühlmittel entweder allein oder im Gemisch mit Wasser
verwendeten mehrwertigen Alkoholen der Angriff der letzteren auf das Magnesium und
seine Legierungen praktisch völlig unterdrückt wird.
Die in der Schlußspalte angegebene Gewichtsveränderung ist ein Maß für den korrodierenden Angriff.The change in weight given in the final column is a measure for the corrosive attack.
