What are the factors affecting the lifespan of Pasteur handheld fluorescence spectrometer in the analysis of hard alloys

The use of alloy materials is increasing in modern industrial development, and their scope of application is also becoming more and more extensive. However, due to the complex composition of alloys, it is often difficult to determine the material composition and quality of alloys with the naked eye or conventional chemical testing methods. The emergence of handheld alloy analyzers has provided new assistance for modern industrial analysis technology.

Hard alloy is an alloy made by powder metallurgy method, mainly composed of powder of one or several refractory carbides (tungsten carbide, titanium carbide, etc.), with metal powder (cobalt, nickel, etc.) added as a binder. It is mainly used for manufacturing high-speed cutting tools and cutting tools for hard and tough materials, as well as for making cold work molds, measuring tools, and high wear-resistant parts that are not affected by impact and vibration.

For the high requirements of casting technology, fluidity is also a very important indicator, which is closely related to factors such as the chemical composition of the alloy, pouring temperature, and filling conditions of the mold. Therefore, professional testing instruments like Pasteur handheld fluorescence spectrometer are naturally needed to "escort" the entire process to ensure the high-quality aluminum alloy required by consumer electronics. Characteristics of Hard Alloy

⑴ High hardness, wear resistance, and red hardness

The hardness of hard alloy at room temperature can reach 86-93HRA, equivalent to 69-81HRC. It can maintain high hardness and excellent wear resistance at 900-1000 ℃. Compared with high-speed tool steel, the cutting speed can be 4 to 7 times higher, the service life is 5 to 80 times longer, and it can cut hard materials with a hardness of up to 50HRC.

⑵ High strength and elastic modulus

The compressive strength of hard alloy is as high as 6000MPa, and the elastic modulus is (4-7) × 105MPa, both of which are higher than high-speed steel. But its bending strength is relatively low, generally ranging from 1000 to 3000 MPa.

⑶ Good corrosion resistance and oxidation resistance

It generally has good resistance to atmospheric, acid, alkali and other corrosion, and is not easily oxidized.

⑷ Small coefficient of linear expansion

When working, the shape and size are stable.

⑸ Shaped products are no longer processed or re ground

Due to the high hardness and brittleness of hard alloys, cutting or regrinding is no longer required after powder metallurgy forming and sintering. When further processing is necessary, only electrical machining such as electrical discharge, wire cutting, electrolytic grinding, or specialized grinding wheels can be used. A product of a certain specification usually made of hard alloy, which is used by brazing, bonding, or mechanical clamping on the blade or mold body.

The application of hard alloy

⑴ Tool material

Hard alloy is used as the largest amount of tool material, which can be used to make turning tools, milling cutters, planers, drills, etc. Tungsten cobalt hard alloys are suitable for short chip processing of ferrous and non-ferrous metals, as well as processing non-metallic materials such as cast iron, cast brass, glued laminated wood, etc; Tungsten titanium cobalt hard alloys are suitable for long chip processing of ferrous metals such as steel. Among similar alloys, those with higher cobalt content are suitable for rough machining, while those with lower cobalt content are suitable for precision machining. The processing life of general hard alloys for difficult to machine materials such as stainless steel is much longer than other hard alloys.

⑵ Mold materials

Hard alloys are mainly used as cold work molds such as cold drawing dies, cold stamping dies, cold extrusion dies, and cold pier dies.

⑶ Measuring tools and wear-resistant parts

Hard alloy is used for wear-resistant surface inlay and parts of measuring tools, precision bearings of grinding machines, guide plates and rods of centerless grinding machines, lathe tips and other wear-resistant parts.

Handheld alloy analyzer is a quantitative analysis of alloy materials using principles such as optics, electronics, mass spectrometry, etc. The alloy analyzer can not only quickly and accurately analyze the composition of alloy materials, but also detect defects, imperfections, etc. It is suitable for analyzing various alloy materials.

When it comes to the service life of a handheld alloy analyzer, there are many factors that affect it, such as the quality of the instrument, the usage environment, maintenance, and other aspects. Generally speaking, the service life of a handheld alloy analyzer is about 3-5 years, and high-quality instruments can be used for a longer time, even up to 7-8 years.

The handheld alloy analyzer has advantages such as high precision, high stability, and fast detection speed, and adopts high-strength materials and waterproof and shockproof designs, which can adapt to harsh usage environments. Regular maintenance, cleaning, and calibration of instruments in daily use can effectively extend their service life.

In addition, the Pasteur handheld alloy analyzer not only plays a key role in industrial production, but is also widely used in various aspects such as environmental monitoring, mineral exploration, and metal material quality monitoring. The emergence of alloy analyzers greatly improves the efficiency and accuracy of analysis and detection, promoting the development and progress of industry.
