Artificial hip joint with joint head and mortar cup surface coated by carbon/TiC nanometer multilayer compound film

The invention discloses an artificial hip joint which plates carbon / TiC nanometer multiple layers of composite membranes on a joint head and the surface of an acetabular cup, the alloy joint head and the surface of the acetabular cup are plated with the multiple layers of the composite membranes which are composed of carbon membranes with the single layer thickness of 12 to 45nm and the carbon / TiC composite membranes with the single layer thickness of 12 to 45nm by mutual interactions, the nanometer multiple layers of composite membranes contain the components as the weight percentages: 85 to 98 percent of carbon and 2 to 15 percent of TiC, and the total thickness of the multiple layers of the composite membranes is 1.5 to 2.5Mum. The multiple layers of the composite membranes on the joint head and the surface of the acetabular cup of the artificial hip joint have excellent invasive property, wear-resistance performance and high load bearing capacity in the simulated human environment, the corrosion prevention function on the alloy is strong, the biological compatibility is good, the histological reaction is low, the invention has no adverse reaction and no allergic reaction in the human body, thereby greatly improving the reliability of the implant materials and the survival service life of the combined artificial hip joint in the human body.

Buoyancy kinetic energy power generation device

The invention discloses a buoyancy kinetic energy power generation device. The buoyancy kinetic energy power generation device is characterized by comprising a buoyancy kinetic energy generation device, a buoyancy kinetic energy amplification and synergism device, a kinetic energy transmission device and a bidirectional integrated kinetic energy integration and slow release device. By means of thebuoyancy kinetic energy power generation device, the kinetic energy of the water flow is converted into longitudinal stable and controllable buoyancy kinetic energy to drive the device to drive a generator to generate electricity by virtue of the constant current of the mountain range drop or the general drop water level of the river, and the device can also directly utilize the natural fluctuation of the ocean to generate electricity. The power generation mode is wide in resource distribution area, can be implemented by many different modes, can generate power without interruption and energystorage equipment, is not influenced by area, time and weather, and is stable in productivity, high in energy efficiency and long in service life; and related components can be prefabricated in a factory mode, and the construction is simple and the cost is low. The buoyancy kinetic energy power generation device has practical implementation and application values and many different implementationmodes; and according to the device, fuel consumption is not needed, the environment is not affected with zero emission, the electric energy requirement urgently needed by development can be effectively met, and the pollution of combustion emission to the human environment at present can be changed.
