FORMING METHOD OF BIO-CERAMIC COATING LAYER HAVING MULTI GRAIN COATING LAYER SIZE AND COATING LAYER THEREOF

摘要

An embodiment of the present invention relates to a method for producing a bio-ceramic film having a composite film particle diameter and a bio-ceramic film according to the same. The technical problem to be solved of the present invention is to provide a method for producing a bio-ceramic film having a composite film particle diameter and a bio-ceramic film according to the same, wherein purity and crystal have the properties of the original material because phase separation does not occur during a film forming step, and in vivo activation is high because surface adhesion and surface roughness are high. The method of the present invention comprises the steps of: providing a bio-ceramic powder having a powder first particle diameter range from a powder supplying unit and transferring the bio-ceramic powder using a transferring gas; and producing a bio-ceramic film by making the transferred bio-ceramic powder collided with a base material in a processing chamber at a speed of 100 to 500 m/s in order to be pulverized, wherein the bio-ceramic film is mixed with a first bio-ceramic particle having a film first particle diameter range and a second bio-ceramic particle having a film second particle diameter range which is larger than the film first particle diameter range. The film first particle diameter range of the first bio-ceramic particle is 1 to 900 nm, and the film second particle diameter range of the second bio-ceramic particle is 900 nm to 10 μm.
