4 Common Metal Surface treatments to Date

The Concept of Metal Surface Treatment It refers to the process of changing the surface condition and properties of parts and optimizing its combination with matrix materials to meet the predetermined performance requirements by using the edge new technologies of modern physical, chemical, metallurgy and heat treatment disciplines. Classification of Metal Surface Treatment Technologies 1. Surface modification The surface chemical composition of the material is not affected by changing the surface microstructure and stress state of the material. 2. Surface Alloying Technology Adding new materials into the matrix to form alloying layer. 3. Surface film technology Chemical reaction between additive … Read more

What is Cast Iron?

For most guys working in the industry of metal machining, Cast iron must be a kind of familiar material. What is cast iron? First of all, it’s a sort of ferro-carbon alloy that contains more than 2.11% of carbon and small amounts of Si, Mn, S, and P. The mechanical properties of cast iron are lower than that of cast steel. But it has excellent castability, shock absorption, wear resistance and cutting machinability. The production process is simple and the cost is low. It is one of the most commonly used metal materials in engineering. Classification of Cast Iron The … Read more

8 Common Microstructures of Metal and Alloy

Modern materials can be divided into four categories: metals, polymers, ceramics and composite materials. Despite the rapid development of macromolecule materials, steel is still the most widely used and most important material in the current engineering technology. What factors determine the dominant position of steel materials? Now let’s introduce it in detail. Iron and steel are extracted from iron ore, rich in sources and low in price. Iron and steel, also known as iron-carbon alloy, is an alloy composed of iron (Fe) and carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other small elements (Cr, V, etc.). … Read more

Application of ultrafine grain cemented carbide

What is ultra-fine grain tungsten carbide ? Ultra-fine grain cemented carbide is a high hardness, high strength and high wear resistance both carbide, and the processing of mutual adsorption – diffusion effect is small, suitable for processing heat-resistant alloy steel, titanium, high High strength non-metallic brittle materials and metal materials such as glass, marble, granite, Plastic reinforced glass fiberboard and other cutting and non-ferrous metals tungsten, molybdenum and other alloy processing. Great Cutting Tool Material As the ultra-fine grain cemented carbide with high toughness and strength, high hardness and wear resistance, so as a cutting tool to obtain high-precision edge, … Read more

14 Common Types Of Porous Materials

UPAC separates pores into micropores (<2 nm), mesopores or mesopores (2 to 50 nm), macropores (> 50 nm) according to the pore size scale; according to the latest definition, the pores are subdivided into Micropores (<0.7 nm) and micropoles (0.7-2 nm), while wells below 100 nm are collectively referred to as nanopores. So how are the names of these hole materials come from? MCM series MCM is short for Mobil Composition of Matter. Mainly by the Mobil Oil researchers, using ethyl silicate as a silicon source, synthesized by a micelle-based soft template method. MCM The Musketeers are MCM-41, MCM-48 and … Read more
