Method for detecting chemical components of metal material

Abstract

The invention relates to the technical field of metal detection, discloses a method for detecting chemical components of a metal material, and aims to solve the problems that existing detection methods are difficult to accurately measure the contents of cobalt, chromium and carbon on the metal material, whether the current contents of cobalt, chromium and carbon exceed standards cannot be known, and the existing detection methods mostly need to add HF, so that the detection efficiency is high. The method comprises the following steps: S1, drying a to-be-detected metal material in a vacuum oven at 95-115 DEG C for 1.5 hours, taking out the metal material, adding a sodium hydroxide solution into a transparent container, adding the metal material into the sodium hydroxide solution, standing for 5-10 minutes, and observing whether the sodium hydroxide solution is changed or not. According to the detection method, light absorption values and working curves are compared and analyzed one by one, the multi-level area sizes of particles with different particle sizes are counted, the actual content of cobalt, chromium and carbon is determined according to the density and distribution area of the particles with different particle sizes, and the content of cobalt, chromium and carbon on the metal material can be accurately measured.

Description

A method for detecting chemical composition of metal materials technical field [0001] The present invention relates to the technical field of metal detection, in particular to a method for detecting the chemical composition of metal materials. Background technique Metal materials generally refer to pure metals or alloys in industrial applications, and there are about 70 kinds of pure metals in nature, Among them, iron, copper, aluminum, tin, nickel, gold, silver, lead, zinc, etc. are common, and alloys often refer to two or more metals or gold It is a material that is combined with a non-metal and has metallic properties. Common alloys such as steel alloys composed of iron and carbon, copper and The alloy formed by zinc is brass, etc. After the metal material is produced, it will be coated on the metal surface with different uses due to different uses. The same chemical composition, in order to ensure normal use, it is necessary to test the chemical composition of th...

Problems solved by technology

[0003] Existing detection methods are difficult to accurately measure the content of cobalt, chromium and carbon on metal materials, and it is impossible to know whether the current content of cobalt, chromium and carbon exceeds the standard. At the same time, most of the existing detection methods need to add HF, which has certain safety Hidden danger
