There have 2 types of coating in Carbide insert ,PVD and CVD coating . PVD coating carbide insert mainly used for machining stainless steel and High-temperature alloy,CVD coating carbide insert mainly used for machining all kinds of steel and cast iron . if you know the difference of this 2 coatings ? here ,let me share more details about it . PVD and CVD are coating techniques. PVD stands for physical vapour deposition , CVD stands for chemical vapour deposition. The key difference between PVD and CVD is that the coating material in PVD is in solid form , in CVD it is in gaseous form.  another important difference we can say that in PVD technique atoms are moving and depositing on the substrate while in CVD technique the gaseous molecules will react with the substrate. Besides, the deposition temperatures between PVD and CVD also different , for PVD, it deposits at a relatively low temperature (around 250°C~450°C) whereas, for CVD, it deposits at relatively high temperatures in the range of 450°C to 1050°C. We,Zhuzhou Apple carbide tools co.,ltd is a professional manufacture for carbide cutting tools ,carbide insert is our hot selling products ,Any interesting ,welcome to contact us for more details ,thanks!

Market demand trends With the technological progress of petroleum, mining, automobile, machinery and other related industries, the upgrading of Chinese tungsten carbide market will be accelerated, and the general low-end product market will gradually shrink. Demand for solid carbide tools, ultra-fine grain size carbide and large special-shaped products continues to increase. Although the concentration for tungsten carbide industry is relatively low and the competition is relatively scattered, the specialized products of different manufacturers are quite different, and their bargaining power for downstream will depend on the product and demand. Chinese high-end manufacturing industry has entered a golden growth period, providing a good opportunity for it’s carbide industry. The stable development of the downstream market will help the future demand of the industry. Market competition trends From the current status, the future competition of tungsten carbide industry will still have a relatively fierce competition pattern in the future with the development of the industry and the expansion of downstream demand. Although the price of some products of relevant enterprises in Chinese carbide market is currently higher than that of foreign enterprises, the price-performance ratio of some products is slightly lower than that of some foreign enterprises, especially in terms of product service life. Chinese tungsten carbide still need continuous and in-depth research and development. The market competition trend should focus on improving the life of product tools, and under the same conditions, product quality and service life should be given the top priority in development.

Halloween, which falls on 1 November every year, is a traditional Western holiday. However, it is now celebrated on the eve of All Saints' Day on 31 October. There are many origins of Halloween, but one of the more plausible ones is legend. Halloween has been celebrated by the Celts (CELTS) living in Ireland, Scotland and other parts of the world since 500 BC. The Celts (CELTS) brought the holiday forward by one day, to 31 October. They considered this day to be the official end of summer, the beginning of the New Year and the start of the harsh winter season. It was believed at the time that the spirits of the dead would return to their homes on this day to find life in the living and be reborn. And, it was the only hope for rebirth after one's death. It was the only hope for regeneration after death. The living, on the other hand, fear that the spirits of the dead will come and take their lives, so people extinguish their fires and candles on this day. On this day, the fires and candles are extinguished so that the spirits of the dead cannot find the living. They turn themselves into demons and monsters and scare away the spirits of the dead. Afterwards, they relight the fire and candles and start a new year. A cold winter is approaching and the spirits of the ancestors have been worshipped. Food has been stored up for the winter.  

Tungsten is a particularly hard metal with a high melting point. Pure tungsten metal typically is not normally used in cutting tools, but tungsten carbide is. In cutting tools, tungsten carbide ceramic particles are bonded together using cobalt metal, which adds fracture toughness to the tool. ceramics are brittle (low fracture toughness) with high strength, while metals tend to have high fracture toughness but low overall strength, so tungsten carbide-cobalt parts have a nice balance of these properties. They are strong enough to cut hard materials and tough enough to last a long time. It can be sharpened but most tool holders allow tungsten tips to be rotated if the tool gets dropped on the tip a piece may break off meaning there will no longer be good support for the tip if rotated to the next sharp side. They are easily replaced but can be expensive depending on shape eg spiral cutter tips for thicknessers. From the perspective of tool materials, high-speed steel, cemented carbide, ceramics, cermets, and even superhard tools, the advancement of material technology has opened up more possibilities for cutting tools. Due to a series of excellent properties such as high hardness and wear resistance, tungsten carbide has gradually become a very important tool material.
