Definitions

  • the present invention relates to a method according to the pre-characterising clause of claim 1.
  • the object of the present invention is to provide such improved adhesion and this is achieved by the combination of measures specified in the characterising part of claim 1.
  • the method according to the invention affords a number of advantages, it being possible to work with a greater number of variations in temperature, particle sizes and material combinations than has hitherto been possible. This makes it easier to select what process parameters are to be used in order to achieve desired characteristics in terms of adhesion and optimum setting.
  • Fig. 1 illustrates the pre-treatment of a part of the surface 2 of a component 1 of a composite material.
  • the relevant component surface 2 is degreased using acetone, for example.
  • the surface 2 is then lightly sanded using a fine abrasive paper or abrasive nylon 3 in order to remove irregularities and raise the surface somewhat. Finally the surface 2 is degreased and dried again.
  • Fig. 2 shows how a layer 4 of a thermosetting adhesive, here in the form of an adhesive film, is applied to the surface 2 pre-treated in accordance with Fig. 1.
  • a layer 4 of a thermosetting adhesive here in the form of an adhesive film
  • this can be applied, for example, by spraying or applying it with a brush.
  • a number of different adhesive layers are feasible, for example epoxy adhesive, acrylic adhesive, urethane adhesive or phenolic plastic-based adhesive.
  • Fig. 3 shows how the thermosetting adhesive layer 4 is heated up by means of a heat gun 5 to a temperature close to the gel point of the adhesive. This gives the adhesive layer a very good adhesive capacity. It will be obvious that the adhesive layer 4 can be heated in some other way to that illustrated in Fig. 3, for example in an oven or the like.
  • Fig. 4 shows the application by spraying of a binder in particulate form.
  • the particulate form may be powder or short fibre lengths of the material.
  • the particles can be applied by scattering on or applying them to the adhesive surface in some other way, so that the particles partially penetrate the latter.
  • Fig. 5 shows how, after application of the binder, the component 1 is placed in an oven 7 or the like for heating to the thermosetting temperature of the adhesive layer 4, so that this is made to set, which means that an excellent adhesive bond is obtained between the adhesive layer 4 and the composite material.
  • Fig. 6 shows how the pre-treated surface 2 provided with the adhesive layer 4 is coated with a layer 6 of an additional material by thermal spraying, for example flame spraying.
  • This additional material may be any of the following: a ceramic; metal oxide; metal; metal alloy or plastic.
  • the temperature of the sprayed material can be adjusted through the choice of spraying method.
  • feasible spraying methods include, for example, arc spraying, plasma spraying or detonation spraying.
  • the application temperature can be varied from approximately 50°C to several hundred degrees Celsius through the use of different spraying methods and additional material.
  • Adhesive is selected having regard to the additional material and application temperature, so that the best possible strength and surface layer quality of the coating 6 can be achieved.
  • Fig. 7 shows the finished component 1 after it has been coated with a layer 6 of an additional material and the adhesive layer 4 has been set by the method according to the invention.
