The present invention relates to a surface modification method for increasing cell activities on an implant material and a TiO_2 layer formed on the surface thereof. More specifically, the dental implant surface modification method is used to execute a surface treatment operation in a nitrogen atmosphere while UV rays are irradiated in order to modify a hydrophobic surface of the implant to a hydrophilic surface without changing the unique physical properties of the implant surface regarding the physically or chemically formed oxide layer, metals, metal alloy, or oxides. The method can also be used to form Ti-N couplings on the implant surface to increase the affinity of proteins and bone cells in order to enhance the initial bone coupling and osseointegration thereof. The method of the present invention can modify the surface of an alloy material to a hydrophilic surface by removing hydrocarbon thereon through the UV rays irradiated in the nitrogen atmosphere for the certain amount of ...

REMOVABLE SET ANCHOR BOLT

Номер: KR101544516B1
Автор: MOON, CHANG, KIM, YOUNG JOON, JANG, GEUN TAE, OH, NAM SICK
Принадлежит: SAMSUNG C&T CORPORATION, OH, NAM SICK

The present invention relates to a removable set anchor bolt including: a fixing bolt which has a screw thread along an outer circumference, and has a taper part (110) whose diameter increases gradually as going to the end on the bottom, and is installed in a hole of a concrete structure; a sleeve (200) which is formed in a cylinder shape, is inserted into the fixing bolt (100), and comprises an extended part (220) which closely adheres to the inner circumference of the hole of the concrete structure by being spread outward when the extended part is geared to the taper part (110) by providing a number of cutting grooves (210) up and down on the bottom; and an elastic member (300) which supports the bottom of the fixing bolt (100) by being installed on the bottom of the hole of the concrete structure, and is lowered as being compressed when an external force above a fixed intensity is applied up and down. When the top of the fixing bolt (100) is hit by the external force above the fixed ...
