Abstract

Partial aluminizing technology on compound material piece, the steps: 1) To confirm aluminizing field and non-aluminizing field by lining, 2) To stick medical belt to protect the non-aluminizing field. 3) To blow grit on the surface of aluminizing field. 4) To clean the surface after blowing grit. 5) To aluminize. 6) To take the medical belt antiabrasion layer down. 7) To measure the resistance value of aluminizing field. The advantage is: It doesn' t need to stick antiabrasion layer for second time on non-aluminizing field after blowing grit, the medical can be straightly taken down after aluminizing, it doesn' t need to be delivered and cleaned, so it save labor and time, it improves the quality of product, and it avoids the hidden trouble on quality of product, and the cost is also decreased.

Description

Composite material element surface local aluminum spraying technique

Technical field: the invention is to be used in the machinery part surface local aluminum spraying made from matrix material; It is improvement to local aluminum spraying technique.

Background technology: before; in the composite material element surface local aluminum spraying technique non-aluminium-plated zone is protected; be to have adopted the trade mark to carry out the pad pasting protection for the 3M adhesive tape; the 3M adhesive tape is coating one deck glued membrane on sheet lead; heating back glued membrane easily breaks away from; also handy 3M adhesive tape will be subsidized the film protection again to the damaged and distortion that the 3M adhesive tape that has pasted produces after blast is handled aluminium-plated region surface; second protection appears; waste material; also waste man-hour; when the 3M adhesive tape was dismantled in aluminium-plated back, the 3M adhesive tape can produce the transfer of part glued membrane, and the glued membrane of transfer is not only thin but also disperse; must clean; cleaning is wasted time and energy, and causes composite material element surface cleaning dirty often, stays hidden danger of quality to next procedure.

Summary of the invention: the purpose of the invention provides and a kind ofly saves time, laborsaving, reduces the composite material element surface local aluminum spraying technique of machinery part surface that matrix material the makes hidden danger of quality after aluminium-plated; Its processing step is as described below:

1). use marking tool to rule at composite material element surface; Determine aluminium-plated zone and pad pasting protection zone;

2). the pad pasting protection is carried out in non-aluminium-plated zone: paste two-layer medical adhesive tape in non-aluminium-plated zone and protect;

3). aluminium-plated surface is handled: handle with blast;

4). aluminium-plated surface is cleaned: with acetone to aluminium-plated surface cleaning;

5). aluminium-plated:

6). the dismounting protecting materials:

7). measure aluminium-plated regional aluminium lamination resistance value.

The advantage of the invention: owing to adopt two-layer medical adhesive tape to carry out the pad pasting protection to the non-aluminium-plated zone of composite material element, at the bottom of medical adhesive tape is yarn fabric, glue is easily on the fiber attached to yarn fabric, difficult drop-off, not fragile medical adhesive tape pad pasting when blast is handled, medical adhesive tape is under moment high temperature, the not yielding and distortion of adhesive tape, because the medical adhesive tape adhesive capacity is poor, be difficult for causing that glue-line shifts again, do not influence the protection effect, so will cancel the secondary pad pasting protection step behind the blast and dismantle the material that saves cleaning and consumed in the protecting materials step, therefore laborsaving saving time saved the technology auxiliary material, reduces manufacturing cost; Do not shift because of medical adhesive tape does not produce glued membrane, avoid producing hidden danger of quality, thereby improved quality product.

Description of drawings:

Fig. 1 is a composite material element surface local aluminum spraying and pastes medical adhesive tape protection zone synoptic diagram.

Embodiment:

Composite material element surface local aluminum spraying technique: its step:

1). use marking tool to rule: to determine that aluminium-plated zone and non-aluminium-plated zone protect with pad pasting at composite material element surface; With Fig. 1 is that example: Fig. 1 is the mechanical component that adopt matrix material to make, its surface local aluminum spraying and the non-aluminium-plated pad pasting protection zone synoptic diagram that needs, 1 promptly has the section line zone to be aluminium-plated zone shown in the figure, and 2,3,4 zones shown in the figure are the non-aluminium-plated zone that needs the pad pasting protection; By regional available conventional measurement facility line shown in Figure 1, also can rule with model, determine aluminium-plated and non-aluminium-plated zone;

2). the pad pasting protection is carried out in non-aluminium-plated zone: paste two-layer medical adhesive tape in non-aluminium-plated zone and protect; By 2,3,4 zones as shown in fig. 1, non-aluminium-plated zone that step 1 is determined, paste two-layer medical adhesive tape and protect;

3). aluminium-plated surface is handled: 1 zone shown in the figure is handled with blast technology;

4). aluminium-plated surface is cleaned: clean with the aluminium-plated surface that acetone is handled blast, remove sand grains and dirt;

5). aluminium-plated: as to carry out aluminium-plated to 1 zone shown in the figure with existing aluminium-plated technology;

6). dismounting protecting materials: the medical adhesive tape protective layer that paste in non-aluminium-plated zone is dismantled; Medical adhesive tape is under moment high temperature, the not yielding and distortion of adhesive tape, poor because of adhesive capacity again, glued membrane is difficult for shifting, but do not influence the protection effect, increase because of having pasted two-layer medical adhesive tape thickness again, therefore dismounting easily is easy to operate, time saving and energy saving, save the auxilliary material of technology, improved quality product, avoided product to produce hidden danger of quality;

7). measure aluminium-plated regional aluminium lamination resistance value: measure with prior art.
