cemented

Cemented是一个英语单词，意思是“水泥固定”。在医学领域，cemented通常指的是人工关节置换手术中使用的一种技术，即通过将人工关节与骨骼固定在一起，以增强稳定性和持久性。

在人工关节置换手术中，医生会先将受损的关节组织切除，然后用金属或塑料等材料制成的人工关节代替。为了确保人工关节与骨骼之间的稳定性，医生需要使用一种特殊的水泥将它们固定在一起。这种水泥通常是一种聚甲基丙烯酸甲酯（PMMA）复合物，可以在体内硬化并形成牢固的连接。

虽然cemented技术已经被广泛应用于人工关节置换手术中，但它仍然存在一些风险和限制。例如，如果水泥未正确固定或未正确硬化，可能会导致人工关节移位或松动。此外，一些患者可能对水泥中的化学物质过敏，导致不良反应。

总的来说，cemented技术是一种有效的人工关节置换手术技术，但医生需要在手术前仔细评估患者的情况，并在手术中谨慎操作，以确保最佳效果。

cemented carbide

Cemented carbide, also known as tungsten carbide, is a composite material made of tungsten carbide particles bonded together by a metallic binder, typically cobalt. It is a very hard and wear-resistant material, making it ideal for use in cutting tools, mining machinery, and other applications where durability is essential.

The manufacturing process for cemented carbide involves mixing tungsten carbide powder with a binder material and then pressing the mixture into the desired shape. The part is then sintered at high temperatures to bond the particles together and create a dense, hard material.

One of the key advantages of cemented carbide is its high hardness and toughness, which makes it ideal for use in cutting tools. It can withstand high temperatures and pressures without deforming or breaking, making it ideal for use in machining applications. Additionally, cemented carbide is highly resistant to wear and corrosion, making it a popular choice for mining and drilling equipment.

Overall, cemented carbide is a versatile and durable material that is used in a wide range of industrial applications. Its unique properties make it ideal for use in cutting tools, mining machinery, and other applications where strength and durability are essential.

Cemented是指使用水泥将两个物体粘合在一起的过程。这种技术广泛应用于建筑、道路、桥梁等领域。水泥是一种常见的建筑材料，它由石灰、硅酸盐和其他材料混合而成。当水泥与水混合时，它会形成一种坚硬的物质，这种物质可以用来固定和粘合各种材料。在建筑中，水泥被用来连接砖块、石头和混凝土。这种连接方式非常牢固，可以使建筑物更加稳定和耐久。在道路和桥梁建设中，水泥被用来连接不同的路面材料，以确保道路和桥梁的平稳和安全。总之，cemented技术是一种非常重要的建筑技术，它为我们的生活提供了许多便利。

cemented carbides

Cemented carbides, also known as hard metal or tungsten carbide, are composite materials made of tungsten carbide particles bonded together by a metallic binder, usually cobalt. They are known for their exceptional hardness, wear resistance, and toughness, making them ideal for use in a wide range of industrial applications.

Cemented carbides are commonly used in cutting tools, such as drills, end mills, and inserts, as well as in wear parts, such as nozzles, valves, and bearings. They are also used in mining and construction equipment, as well as in the aerospace and automotive industries.

The properties of cemented carbides are determined by the size and distribution of the tungsten carbide particles, as well as the amount and type of binder used. The higher the percentage of tungsten carbide, the harder and more wear-resistant the material will be. However, higher tungsten carbide content also results in lower toughness and increased brittleness.

Cemented carbides can be produced using a variety of manufacturing processes, including powder metallurgy, hot isostatic pressing, and injection molding. The choice of process depends on the desired properties, as well as the size and complexity of the part being produced.

Overall, cemented carbides are a versatile and durable material that have revolutionized many industries. Their unique combination of hardness, wear resistance, and toughness make them an indispensable part of modern manufacturing.
