GB/T 20255.4-2006 Methods for chemical analysis of hardmetals—Determination of cobalt, iron, manganese, molybdenum, nickel, titanium and vanadium contents—Flame atomic absorption spectrometric method
Abstract
This part specifies the method for determining the content of cobalt, iron, manganese, molybdenum, nickel, titanium, and vanadium in carbides of chromium, niobium, tantalum, titanium, tungsten, and vanadium, as well as mixtures of these carbides with bonding metals, and hard alloys (including hard alloys with completely removed coatings).
This part is applicable to the determination of the content of cobalt, iron, manganese, molybdenum, nickel, titanium, and vanadium in carbides of chromium, niobium, tantalum, titanium, tungsten, and vanadium, as well as mixtures of these carbides with bonding metals, and hard alloys (including hard alloys with completely removed coatings). The measurement range is 0.5% to 2%.
