硬质合金刀头刀片回收材质性能介绍

发布时间:2021-09-02 来源:http://www.jnskdj.com/ 作者:admin

硬质合金又名钨钢,是采用优良碳化钨+钴粉料经配方配比混合后通过压制烧结制成,具有高硬度、高强度、高耐磨性和高弹性模量,属于粉末冶金工业。硬质合金作为现代工业的牙齿,硬质合金刀具对制造业的发展起着基础性的推动作用。

Cemented carbide, also known as tungsten steel, is made by pressing and sintering with excellent tungsten carbide + cobalt powder after formula mixing. It has high hardness, high strength, high wear resistance and high elastic modulus. It belongs to the powder metallurgy industry. As the teeth of modern industry, cemented carbide tools play a fundamental role in promoting the development of manufacturing industry.

硬质合金按晶粒大小区分,可分为普通硬质合金、细晶粒硬质合金和亚细、超细晶粒硬质合金,新推出的双晶硬质合金。按主要化学成分区分,可分为碳化钨基硬质合金和碳化钛基硬质合金。

According to the grain size, cemented carbide can be divided into ordinary cemented carbide, fine grain cemented carbide, sub fine and ultra-fine grain cemented carbide, and the newly launched bicrystal cemented carbide. According to the main chemical composition, it can be divided into tungsten carbide based cemented carbide and titanium carbide based cemented carbide.

碳化钨基硬质合金包括钨钴类(YG)、钨钴钛类(YT)和添加稀有碳化类(YW)三类,它们各有优缺点,主要成分为碳化钨(WC)、碳化钛(Tic)、碳化铌(NbC)等常用的金属粘接相是Co。

Tungsten carbide based cemented carbides include tungsten cobalt (YG), tungsten cobalt titanium (YT) and rare carbide (YW). They have their own advantages and disadvantages. The main components are tungsten carbide (WC), titanium carbide (TIC) and niobium carbide (NBC). The commonly used metal bonding phase is Co.

碳化钛基硬质合金是以Tic为主要成分的硬质合金,常用的金属粘接相Mo和Ni。硬质合金具有硬度高(86~93HRA,相当于69~81HRC)仅次于金刚石、热硬性好(可达900~1000℃,保持60HRC);抗弯强度高(MPa5100)、良好的抗冲击韧性和抗腐蚀性极高的化学惰性等一般合金刀片所没有的特性。

Titanium carbide based cemented carbide is a cemented carbide with tic as the main component, and the commonly used metal bonding phases are mo and Ni. Cemented carbide has high hardness (86 ~ 93HRA, equivalent to 69 ~ 81hrc), second only to diamond, and good thermal hardness (up to 900 ~ 1000 ℃, maintained at 60HRC); High bending strength (mpa5100), good impact toughness and high corrosion resistance, chemical inertia and other characteristics that general alloy blades do not have.
