Abstract

PURPOSE:To manufacture on ornamental material of novel design by putting mosaically noble-metla material pieces having difference in melting point on the surface of a noble-metal base material and by heating the base material into semimolten state. CONSTITUTION:The surface of the sheet-like or bar-shaped base material 1 consisting of a noble metal such as Au, etc., or a noble-metal alloy is inlayed with the noble-metal material pieces 2 such as Pt, etc., having difference in melting point as compared with the base material 1 and different in color tone into the mosaic condition of required design. This material is heated by means of a torch burner, etc., up to a temp. right under the melting point where the base material 1 is formed into semimolten state, so that noble-metal material pieces 2 are diffused into the base material 1. In this way, a mosaic cladding material for ornamental and personal-ornament material can be manufactured with high operability.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for manufacturing a cladding material having a fixed mosaic pattern suitable for use as a decorative material or an ornamental material.

[Conventional technology]

Conventionally, designs such as discontinuous geometric patterns created by combining precious metals of different tones on parts of decorative materials and accessories have been created using waxing or inlay methods.

[Problem that the invention seeks to solve]

However, with conventional manufacturing methods, the pattern is a uniform geometric pattern with a simple design, which is poor in terms of design.

In addition, these brazing methods and inlaying methods require special skills from experts and have poor workability, making them unsuitable for mass production.

[Means for solving problems]

On the surface of a plate-shaped or rod-shaped base material made of a precious metal or a precious metal alloy, pieces of one or more different colors of precious metal materials having a melting point different from that of the base material are dispersed in a desired design on the surface of the base material, and then they are placed in a furnace. By setting the temperature to just below the melting point of the base material, which indicates a semi-molten state, and introducing the base material with the above-mentioned precious metal material pieces dispersed into the furnace, the precious metal material pieces are diffused on the surface of the base material to create a mosaic-patterned cladding. This is the manufacturing method for obtaining the material.

〔Example〕

One embodiment of the invention is fully described below.

The figure is a perspective view showing one embodiment of the present invention.

1 is a base material made of a noble metal or a noble metal alloy material, and 2 is a pattern piece made of one or more kinds of noble metals or noble metal alloys which are shimmered in a mosaic shape.

The base material 1 is heated by placing the scattered υ fit pattern pieces 2 in a mosaic pattern on the surface of the base material 1, and heating the base material 1 under a furnace with a burner until the base material 1 reaches a melting point below 1, that is, a semi-molten state. The pattern piece 2 can be completely diffused.

The thus diffused T-clad material is annealed and cold-rolled repeatedly to form a plate material of an appropriate thickness according to the material of the ornament or accessory, thereby producing a mosaic-patterned clad material.

The present invention will be explained in detail below.

1 Thickness 10 x width 50 + mn x length 10 mm yellow base material made of Au 1 Predetermined pattern piece 2 to be patterned on a board Amorphous OPt with size 0.5 m x about 10 -
Scatter the pieces into a mosaic of the desired design.

The pattern pieces 2 are scattered on the surface of the base material 1 to form a material, and this material e is heated with a torch burner to just below the melting point at which the base material 1 is in a semi-molten state, whereby the base material 1 and the pattern pieces 2 are diffused to form a mosaic. You can get pattern materials.

This material was further annealed and cold-rolled repeatedly to form a plate material of a predetermined thickness, and the material was cut into a 417-inch shape to produce a ring.

On the surface of the yellow base material 1, which is a 20w%Ag5w%Cu alloy, 0.51X5φ 75W%Au 25w%Pd
Pattern pieces 2 (i-) are arranged in a mosaic pattern with a desired design and heated in a high-frequency furnace in a mixed atmosphere of N2 gas and N2 gas, resulting in the skin effect and electroimaging effect of the high-frequency induction heating phenomenon. The base material 1 and the pattern piece 2 were diffused to form a material with a mosaic pattern, and the obtained material was cut and formed by pressing, etc., and then the materials were made into a pendant head.

3. 58.5s of thickness 5 lid x width 100 x length 100 x 58.5s
v%Ag 20.75w%Ag 20.75w%
A thickness of 0.1+mX is applied to the surface of the yellow base material 1, which is a Cu alloy.
Pattern pieces 2 of about 1°mj of white pieces of 60w%Pa 40w%Ag and red pieces of 58.5W%Au 41.5w%Cu are scattered throughout the whole in a mosaic shape.

Electric furnace? In a mixed atmosphere of N2 gas and N2 gas,
When the base material 1 is heated to just below the melting point at which it becomes semi-molten, the base material 1 and the pattern pieces 2 are diffused to obtain a mosaic-patterned material, and the material is fully annealed.

After repeated cold working, a compact case was produced with a thickness of one inch.

Above J: By heating the material to a semi-molten state with the base material, the pattern pieces scattered on the surface of the base material and the base material are diffused, creating a clad material with a mosaic pattern.

However, when a high frequency furnace is fully used, diffusion with the pattern piece can occur at a temperature lower than the melting point of the base material due to the skin effect and electroimage.

〔Effect of the invention〕

As described above, the mosaic pattern decorative material according to the present invention is
By arranging the precious metal alloy pieces, which are patterned pieces, on the surface of the base material in an arbitrary pattern and heating the base material in a furnace or burner to a semi-molten state, just below the melting point, the base material and the patterned pieces are diffused, creating a mosaic-like pattern. Not only can a cladding material be manufactured, an innovative design not found in conventional cladding materials with different color tones can be obtained, but it is also highly workable and has the effect of providing a fixed material suitable for mass production.
