preparation example Construction

[0090] The invention further enables the production of three-dimensional structures, wherein parts of the product are used as scaffolds for growing said three-dimensional structures.

[0091] According to the invention there is also provided a carbonitride-coated product comprising a defined surface coated by laser ablation, wherein the coated uniform surface area comprises at least 0.2 dm 2 And the coating has been done by using ultrashort pulse laser deposition, wherein the pulsed laser beam is scanned with a rotating optical scanner comprising at least one mirror for reflecting said laser beam. The benefits obtained from these products are described in more detail in the previous method description.

[0092] In a preferred embodiment of the invention, said uniform surface area comprises at least 0.5 dm 2 . In a more preferred embodiment of the invention, said uniform surface area comprises at least 1.0 dm 2 . The present invention also easily realizes the 2 (such as 1m...

[0102] Example used to illustrate known technical issues - laser technology

[0103] figure 2 represents ITO of different ITO film thicknesses (30 nm, 60 nm, and 90 nm) fabricated on polycarbonate plates (~100 mm × 30 mm) by employing a state-of-the-art optical scanner (i.e., vibrating mirror (galvano scanner)). coating. Although this ITO coating was not deposited on a metal substrate, the figure clearly shows the similarity with the use of vibrating mirrors as optical scanners (usually used especially in ultrashort pulse laser deposition (USPLD) and in laser-assisted coating middle) related issues. When the oscillating mirror changes its direction of angular motion at its end positions, and due to the moment of inertia (moment of inertia), the angular velocity of the mirror is not constant near its end positions. Due to the oscillating motion, the mirror is continuously braked and stopped before being accelerated again, thus causing irregular handling of the target materi...

[0111] Figure 13a shows a target material ablated with a pulsed laser in the picosecond range using a rotary scanner at a velocity that achieves ablation of the target material with adjacent pulses slightly overlapping, avoiding the hurdles of the prior art. Electron scanner related issues. Figure 13b shows a magnified view of a portion of the ablated material, clearly showing the smooth and controlled ablation of material along both the x- and y-axes, and thus the generation of high-quality, particle-free plasma body and further produces high-quality films and coatings. Figure 13c shows an example of a single ablation site possible in x- and y-dimensions achieved by one or a few pulses. Here, it can be clearly seen that the invention achieves ablation of material in such a way that the width of the ablation point is always greater than the depth of the area of ​​the ablation point. Theoretically, possible particles (if they would be generated at all) could now have the maxi...

Abstract

The invention relates in general level to a method for coating articulating surfaces of medical products. The invention also relates to coated medical products manufactured by the method. The coating is carried out by employing ultra short pulsed laser deposition wherein pulsed laser beam is preferably scanned with a rotating optical scanner comprising at least one mirror for reflecting said laser beam. The invention has several both industrially and qualitatively advantageous effects such as high coating production rate, excellent coating properties and overall low manufacturing costs.

Description

technical field [0001] The present invention generally relates to a method for coating (coating, coating) including large surface areas (surface area, surface area) with carbonitride (carbon nitride) by ultra short pulsed laser ablation (ultra short pulsed laser ablation). areas) of various product methods. The invention also relates to products manufactured by this method. The present invention has various advantageous effects such as high coating productivity, excellent coating performance (coating performance), and low manufacturing cost. Background technique [0002] carbonitride [0003] Since Cohen and his colleagues proposed that β-C 3 N 4 (a type similar to β-Si 3 N 4 Carbonitride materials) should have a hardness comparable to diamond, and carbonitride materials have become the focus of considerable experimental and theoretical attention. Subsequent calculations have shown that other crystalline C 3 N 4 should have the same β-C 3 N 4 Equivalent to or high...
