Definitions
- the invention relates to a ceramic material which is particularly suitable for dynamic loads.
- Ceramic materials offer a variety of applications. Their composition can be tailored by specific addition of certain elements and / or their compounds to the intended use.
- Aluminum oxide and zirconium oxide, for example, are ceramic materials which are processed individually or in combination with one another inter alia to cutting tools, catalyst supports or prostheses.
- Ceramic materials are brittle and therefore generally not suitable for dynamic loads, in particular caused by vibrations and shocks.
- the object of the invention is to introduce a ceramic material which is suitable for dynamic loads.
- Material with the ability to absorb energy under dynamic load is suitable.
- this material is particularly suitable for use as
- Protective ceramics ie for the production of components where an energy absorption is required, such as armor, especially bullet plates.
- Alumina in a corresponding addition to 100% by weight Dominant structural component of such a combination of materials is the aluminum oxide. Therefore, the property-determining characteristics such as hardness, modulus of elasticity and thermal conductivity are close to the properties of pure aluminum oxide.
- the constituents zirconium oxide and strontium aluminate are incorporated in the aluminum oxide matrix.
- the raw materials are preferably used in high purity. Due to the high purity of the raw materials, grain boundary phases are formed only to an extremely small extent.
- the strontium aluminate forms characteristic platelet-shaped crystallites, platelets, which contribute significantly to increasing the strength.
- the constituents zirconium oxide and strontium aluminate contribute to increasing the fracture toughness, which is about 60% higher than with pure aluminum oxide.
- the strength is increased almost by a factor of 2
- the damage tolerance that is, the property of the component, even with a possible damage still retain a high residual strength.
- the crack path is surprisingly deflected, so that additional energy is absorbed in the crack propagation.
- a peculiarity of the material according to the invention is to be considered that the two mechanisms mutually reinforce, so that the effective increase in the fracture toughness is even greater than would be expected by simple addition of the individual mechanisms.
- a preferred material composition with its properties is listed below:
- Al 2 O 3 The content of Al 2 O 3 supplements from 72.65 wt .-% to 74.54 wt .-%. Commodity related contaminants ( ⁇ 0.05% by weight) are possible but not listed separately because of their minority.
- the production of sintered bodies from the material according to the invention takes place by means of conventional ceramic technology.
- the main process steps are:
- the properties of the sintered shaped body made of the material according to the invention can still be reinforced by incorporation. It is thus possible to mix whiskers and / or fibers into the material before the formation of a sintered body or to incorporate reticulated structures or fabrics into the material in the green state.
- the whiskers, fibers or nets or webs must be made of a material that does not interact with the ceramic material in such a way that deterioration of its properties occurs. In addition, the material must not change during sintering in such a way that the material is damaged.
- Sinterform body which are made of the material according to the invention, surprisingly combine the best properties of each of the competing ceramic materials alumina and zirconia, especially for use as a protective ceramic in itself: hardness, aging resistance, water wetting behavior and high thermal conductivity are properties High strength and high fracture toughness, that is damage tolerance, are properties known from sintered bodies of zirconia.
