Best Company For the Ceramic Works for You

The main disadvantages of ceramics are its fragility and processing complexity. Ceramic materials do not work well under mechanical or thermal shock conditions, as well as under cyclic loading conditions. They are characterized by high sensitivity to incisions. At the same time, ceramic materials have high heat resistance, excellent corrosion resistance and low thermal conductivity, which make it possible to successfully use them as thermal protection elements.

At temperatures above 1000 ° C, ceramics are stronger than any alloys, including super alloys, and its creep resistance and heat resistance are higher.

The main areas of application of ceramic materials include cutting tools, parts of internal combustion engines and gas turbine engines, etc. In MPF Products Inc you will see all of them.

Cutting ceramic tool

Cutting ceramics are characterized by high hardness, including heat, wear resistance, chemical inertness to most metals in the process of cutting. In terms of the complex of these properties, ceramics significantly exceed the traditional cutting materials – high-speed steels and hard alloys.

Comparative values ​​of properties of instrumental materials

High properties of cutting ceramics allowed to significantly increase the speed of machining of steel and cast iron.

Comparative values ​​of cutting speeds for turning with a ceramic tool and a tool of hard alloy

Aluminum oxide with additives of zirconium dioxide, carbides and nitrides of titanium, as well as on the basis of anoxic compounds – boron nitride with cubic lattice (BN), commonly called cubic boron nitride, and silicon nitride Si 3 N , are widely used for the manufacture of cutting tools . 4 . Cutting elements based on cubic boron nitride depending on the production technology, produced under the names of elbor, borazon, composite 09 and others, have hardness close to the hardness of the diamond tool, and maintain resistance to heating in air to 1300-1400 ° C. Unlike a diamond tool, cubic boron nitride is chemically inert towards alloys based on iron. It can be used for roughing and finishing turning of hardened steels and cast irons of almost any hardness.

Cutting ceramic plates are used for equipping various milling cutters, turning tools, boring heads, special tools.

Ceramic engines

From the second law of thermodynamics it follows that in order to increase the efficiency of any thermodynamic process it is necessary to increase the temperature at the input to the power converter: Efficiency = 1 – T 2 / T 1 , where T 1 and T 2 are the temperatures at the input and output of the power converter device, respectively.

At the same time, it should be noted that a number of unresolved problems remain in the technology of making ceramic engines. These include, first of all, the problems of ensuring reliability, resistance to thermal shocks, developing methods for connecting ceramic parts with metal and plastic ones.
