Semiconductor equipment MOCVD thermal field solution
Semiconductor equipment MOCVD thermal field solution
Metal Organic Chemical Vapor Deposition (MOCVD) is a chip epitaxial technology for preparing mixed semiconductor devices, metal and metal oxide and metal nitride film materials. The heating system is an important part of the MOCVD equipment. Whether it can heat the substrate quickly and uniformly directly affects the quality of film deposition, thickness consistency, and chip performance. The rhenium alloy under Rheniumet has 10 years of professional production technology experience in the production of rhenium heaters for MOCVD and a complete quality control management system. It is a substitute for imported big-name or original parts of rhenium heaters for MOCVD and can carry out OEM full-process foundry. It is the number one domestic manufacturer with the most technical development strength and quality assurance ability.

Friction stir welding solutions
Friction stir welding solutions
The joints obtained by welding magnesium, aluminum, copper, titanium alloys or heavy steel by traditional fusion welding methods have defects such as pores and microcracks, and the heat-affected zone is wide and the deformation is large, which limits the welding structure and restricts the weldment in related fields. Wide range of applications. Friction stir welding (Friction stir welding, FSW) as a new type of solid phase welding technology can effectively solve this problem. Friction stir welding does not require filler metal, the welding heat affected zone is small, the joint deformation is small, and the welding process is free of smoke and dust pollution.

Tooling solutions for harsh working conditions such as high hardness, super hardness, wear resistance, impact resistance, ablation resistance, high torque, high transmission, etc.
Tooling solutions for harsh working conditions such as high hardness, super hardness, wear resistance, impact resistance, ablation resistance, high torque, high transmission, etc.
The industry generally refers to materials with a Vickers hardness HV of 10~40GPa as high-hard materials, generally represented by metal-based or ceramic-based composite materials, such as cemented carbide, silicon carbide, corundum (alumina), etc.; Vickers hardness HV Those larger than 40GPa are called superhard materials, which mainly refer to diamond and cubic boron nitride. Challenging and severe working conditions require materials to meet the conditions of high hardness and wear resistance, as well as harsh requirements such as ultra-high temperature, high strength, impact resistance, high transmission, and large torque.

Tungsten carbide-cobalt (WC-Co) hard alloy is a material with high hardness, excellent wear resistance, and high corrosion resistance. It mainly consists of tungsten carbide (WC) particles and cobalt (Co) metal phase. Tungsten carbide is an extremely hard ceramic material with very high hardness and wear resistance. However, pure tungsten carbide is brittle and difficult to process and use. Therefore, to improve its toughness and processability, tungsten carbide is usually mixed with cobalt powder and then sintered through a high-temperature sintering process. Cobalt acts as a binder between tungsten carbide particles, increasing the alloy's toughness and ductility. Cobalt also helps to enhance the alloy's corrosion resistance, making it more suitable for applications in various harsh environmental conditions.

As one of the representatives of high-temperature alloys, molybdenum-based alloys have been widely used in aerospace, nuclear industry, chemical industry, and other fields. However, there are still some limitations in the mechanical properties and high-temperature stability of molybdenum-based alloys, which has prompted researchers to explore new alloy design strategies and methods of adding alloying elements. Rhenium, as a high-melting point and high-density transition metal, possesses excellent oxidation resistance and corrosion resistance, and thus has been extensively applied in high-temperature alloys. Studies have shown that the addition of rhenium to molybdenum-based alloys can significantly improve the strength, plasticity, and high-temperature stability of the alloys. Furthermore, molybdenum-rhenium alloy materials have broad prospects in aerospace, nuclear industry, and other fields due to their high strength, high temperature durability, and good corrosion resistance. This article will introduce the strengthening effect of rhenium in molybdenum-based alloys and discuss the application prospects of molybdenum-rhenium alloy materials.

High-temperature alloy, also known as heat-resistant alloy or superalloy, refers to a type of metallic material that is composed primarily of iron, nickel, and cobalt. It is capable of long-term operation under high temperatures of 600℃ or above, as well as certain levels of stress. High-temperature alloys possess high strength at elevated temperatures, good oxidation and corrosion resistance, as well as excellent performance in fatigue and fracture toughness. Based on the matrix composition, they can be categorized into three types: iron-based, nickel-based, and cobalt-based alloys. Regarding the production methods, high-temperature alloys can be classified as cast high-temperature alloys, wrought high-temperature alloys, and powder metallurgy high-temperature alloys. Furthermore, they can be strengthened through mechanisms such as solid solution strengthening, dispersion strengthening, precipitation strengthening, and grain boundary strengthening.

Recently, a team of Central South University including Professor Huang Zaiwang and Professor Zhang Lijun published a paper in ACTAMATERIALIA, reporting the latest research trends: the creep resistance and phase stability of nickel-base single crystal superalloy are improved by replacing Re with OS. So, how likely is it that osmium (OS) will replace rhenium (Re) as the most important strengthening element in ni-base single crystal superalloys in practical production and application? Let's read through the core meaning of this paper.
