Abstract
According to various embodiments, a dissimilar metal member according to various embodiments, comprises a first metallic material including a bonding portion, the bonding portion including a pattern formed by a laser; and a second metallic material bonded to the bonding portion of the first metallic material by die casting, wherein a portion of the second metallic material forming contact with the bonding portion of the first metallic material forms a reverse negative of the pattern.
Claims17
A dissimilar metal member comprising:
- a first metallic material including a bonding portion, the bonding portion including a pattern formed by a laser;
- and
- a second metallic material bonded to the bonding portion of the first metallic material by die casting, wherein a portion of the second metallic material forming contact with the bonding portion of the first metallic material forms a reverse negative of the pattern.
A method of manufacturing a dissimilar metal member, the method comprising:
- laser etching a pattern at a bonding portion of a first metallic material;
- injecting molten metal into a mold causing the molten metal to flow to the pattern;
- and
- cooling the molten metal, thereby forming a second metallic material.
A dissimilar metal member comprising:
- a first metallic material including a bonding portion and including stainless steel (SUS);
- a pattern formed at the bonding portion by a laser, wherein a depth of the pattern is less than 500 μm;
- and
- a second metallic material formed by performing die casting that injects molten metal including aluminum (AL) after inserting the first metallic material into a mold so that the molten metal flows to the pattern and is bonded to the first metallic material, wherein a portion of the second metallic material forming contact with the bonding portion of the first metallic material forms a reverse negative of the pattern.
A method of manufacturing a dissimilar metal member, the method comprising:
- forming a pattern including a lattice shape at the bonding portion of a first metallic material using a laser;
- injecting molten metal including aluminum (AL) into a mold so that the molten metal flows to the pattern including the lattice shape after inserting the first metallic material into a mold, thereby forming and bonding a second metallic material to the first metallic material;
- performing a CNC process on the first and second metallic materials;
- and
- performing surface processing on the first and second metallic materials.
