Problems solved by technology

However, the metallurgical bonding portion is a part of the surface of the cast-clad light metal part, and the protruding part of the rough surface becomes tapered, so that the mechanical bonding force between the cast-clad light metal part and the cast-clad light metal is relatively weak. Small

Embodiment Construction

[0045] best practice

[0046]Embodiments of the present invention will be described in detail below with reference to FIGS. 1 to 16 .

[0047] As shown in Figure 1a, the molten light alloy 1 containing Al-73%, Si-17%, Fe-5%, Cu-3.5%, Mg-1% and Mn-0.5% (weight percentage) is obtained from a pot (pot) 2 filling into a crucible 3 . The molten light metal falls through an opening in the bottom of the crucible. At this time, the molten light alloy becomes tiny particles, and is rapidly cooled by air or inert gas sprayed at a high speed from the nozzle 4 around the opening to form a matrix (matrix) hypo / hypereutectic aluminum-silicon alloy powder 5 (atomization process ).

[0048] The matrix sub / hypereutectic Al-Si alloy powder 5 is filled into a mixing container 6 together with wear-resistant alumina powder and self-lubricating graphite powder ( FIG. 1 b ). Then, the mixing container 6 is sealed and rotated around the horizontal axis 7 to uniformly mix the powders to obtain a r...

Abstract

The present invention provides a metal part cast covered by a metal casting, its manufacturing method and a metal casting containing the metal part cast covered. A cast-clad hollow cylindrical metal part having a raised outer surface is manufactured by inserting a hollow cylindrical metal stock 13 into a mold 17 having an interior forming a longitudinal groove of depth H and width W. peripheral surface, and then the hollow cylindrical metal raw material 13 is hot-extruded.

Description

technical field [0001] The invention relates to a cast-clad metal part from a metal casting, a method for producing the cast-clad metal part and a metal cast comprising the cast-clad metal part. Background technique [0002] Light metal parts cast-clad by light metal castings having a rough and uneven outer surface formed by spraying hard rough cone-shaped or sharp particles on the outer surface for shot blasting are known (Japanese Laid-Open Patent Publication Level 10 -94867). [0003] In the cast-clad light metal part described above, the outer surface of the hard and rough particles must have sharp edges in order to roughen the outer surface of the light metal part. [0004] When the outer surface of a cast-clad light metal part is roughened with hard grains, the bottom of the roughened surface forms steep valleys from the sharp edges of the hard roughened grains, but the top of the roughened surface does not necessarily form steep peaks. Also, the hard particles must ...
