Definitions
- the invention relates to method of surface structure replication, creation of an enlarged image or model of surface of technical parts made of metal and non-metal materials.
- Another method of surface replication on a nanostructure scale rests in applying a thin film on the replicated substrate surface; the film is based primarily on cellulose acetate, which after application of softening agent-namely acetone- occupies conformation which exactly copies the surface. After reinforcing and removing the foil in this conformation a thin layer of suitable material; such as gold, platinum, ferrum or carbon, is being applied on the negative established on its surface. This way the replica with nanostructures consistent with the original substrate surface is being produced.
- suitable material such as gold, platinum, ferrum or carbon
- the method of surface structure replication according to the invention contributes to the removal of the above mentioned imperfections of the state of art to a great extent.
- the nature of invention consists in that the surface of the respective part is first covered with a non- transparent mask with a rectangular hole, edges of which correspond to the size of the replicated part of the surface. After that follows the optical scanning of coordinates of this part of the surface, saving coordinates in the form of three-dimensional matrix x, y, z and creating an enlarged replication of the surface by transferring data of the three-dimensional matrix to an enclosed area without gaps with subsequent print-out by 3D print and/or import of the data to the CAD system with automatic generating of the respective tool trajectories for production of an enlarged surface model by means of the CNC machining technology.
- the non-transparent mask is advantageously a mask made of non-transparent thin and elastic material, based mainly on paper or plastic material provided with an adhesive layer.
- the enclosed area without gaps for print-out by 3D print is advantageously generated in standard STL format (stereolitography) with the possibility to set the individual scale for particular x, y, z axes.
- Method of replication according to the invention is particularly convenient when it is necessary to create a replica of the evaluated surface which is interesting from the tribologic point of view. In such case it is possible to display in arbitrary scale a space on which the scanning of surface texture in 2D and 3D, according to relevant ISO standards, was performed. Further it is possible to replicate in arbitrary scale various defects as scratches, fissures or cracks, which occur on the surface of samples and thereby also decrease their quality.
- FIG. 1 - schematic representation of the principle of surface replication according to the invention
- FIG. 2 example of a sample of microhardness evaluation prepared to serve as a model surface replication with a mask applied
- FIG. 3 - 3D image of the enlarged replica of sample surface from microhardness evaluation
- Fig. 4 space enlarged surface replica of the sample from microhardness evaluation (replica created by rapid prototyping technique)
- Fig. 6 - space enlarged replica of the surface of sample made of steel machined by face milling technique (replica made by rapid prototyping technique).
- the sample surface 1 was covered by a paper mask 2 with a limiting opening of a square shape with 0,6 mm edges.
- the area 1 defined by the mask opening 2 was subsequently scanned by a 3D scanner (such as Tailor Hobson with a CLA scanner), in specific distance in x and y axes 0,025 - figure 1 presents scanning in the direction from x to y, or in the y to x direction from the starting point A to the end point Z - as suggested by arrows 3.
- the resolution in the axis was left to maximum, namely 1 nm.
- Fig. 4 presents a well visible replication of the surface sample with a typical imprint of the measuring, already after relaxation.
- Replication of the 12020 steel sample surface made according to the invention presents another practical example of application.
- the sample was tooled by a technique of face milling.
- the scanned surface size for 4mm x 2mm; the remaining process and 3D scanning parameters were identical with Example 1.
- Fig. 5 a 3D image of the surface sample can.be seen which was gained with help of Talymap commercial programme; in Fig.6 can be seen a space replication of the surface which was achieved by the rapid prototyping technique.
