Description
Fleksibel sammensatt gjenstand. Flexible composite object.
Den foreliggende oppfinnelse angår en fleksibel sammensatt gjenstand, spesielt en fleksibel sammensatt gjenstand som har en mot slitasje meget motstandsdyktig overflate. The present invention relates to a flexible composite object, in particular a flexible composite object which has a very wear-resistant surface.
Hittil er gjenstander som har mot slitasje motstandsdyktig overflate blitt an-brakt på maskindeler i form av innsetningsstykker. Disse innsetningsstykker er blitt dannet ved å sintre pulvere av mot slitasje meget motstandsdyktig materiale, f. eks. wolframkarbid. Slike innsetnings-blokker festes til maskindelen ved hjelp av passende midler, f. eks. ved et klebestoff. Den mekaniske forbindelse mellom innset-ningsstykket og bæredelen er forholdsvis svak og lar meget tilbake å ønske. Dessuten har innsetningsstykker av mot slitasje meget motstandsdyktig materiale, som wolframkarbid, som regel meget stor elastisi-tetsmodul og følgelig inntrer det sprekker i disse hvis innsetningsstykkene deformeres selv bare lite. Until now, objects that have a wear-resistant surface have been attached to machine parts in the form of inserts. These insert pieces have been formed by sintering powders of very wear-resistant material, e.g. tungsten carbide. Such insertion blocks are attached to the machine part by means of suitable means, e.g. by an adhesive. The mechanical connection between the insert piece and the carrier part is relatively weak and leaves much to be desired. In addition, insert pieces made of very wear-resistant material, such as tungsten carbide, usually have a very high modulus of elasticity and consequently cracks occur in these if the insert pieces are deformed even just a little.
Den foreliggende oppfinnelse skaffer en fleksibel sammensatt gjenstand som har en mot slitasje meget motstandsdyktig overflate og som er egnet til solid befes-tigelse på en bæredel på et punkt hvor en mot slitasje meget motstandsdyktig overflate kreves. The present invention provides a flexible composite object which has a very wear-resistant surface and which is suitable for solid attachment to a support part at a point where a very wear-resistant surface is required.
På den vedføyde tegning er On the attached drawing is
fig. 1 et perspektivriss av en fleksibel sammensatt gjenstand i henhold til oppfinnelsen, som har en mot slitasje meget motstandsdyktig overflate. fig. 1 is a perspective view of a flexible composite object according to the invention, which has a very wear-resistant surface.

Fig. 3 viser et mikrofotografi med 300 gangers lineær forstørrelse av en fleksibel basisplate av metall og den dermed mekanisk forbundne mot slitasje meget motstandsdyktige flate. Fig. 3 shows a photomicrograph with 300 times linear magnification of a flexible metal base plate and the thus mechanically connected to wear very resistant surface.
I henhold til den foreliggende oppfinnelse dannes den på tegningen viste sam-mensatte gjenstand 10 av en tynn fleksibel basisplate av metall 12, som har et smeltepunkt over ca. 315° C, og av et tynt over-flatelag av et normalt ikke fleksibelt hårdt materiale 14 som er forbundet med basisplaten, hvor det hårde overflatemateriale har en laminær struktur, en porøsitet under ca. 3 %, og en tetthet som er praktisk talt lik massetettheten av et massivt støpt hårdt overflatemateriale av den samme sammensetning. According to the present invention, the composite object 10 shown in the drawing is formed from a thin flexible base plate of metal 12, which has a melting point above approx. 315° C, and of a thin surface layer of a normally inflexible hard material 14 which is connected to the base plate, where the hard surface material has a laminar structure, a porosity below approx. 3%, and a density which is practically equal to the mass density of a solid cast hard surface material of the same composition.
Overflatebelegg av høytsmeltende mot slitasje meget motstandsdyktige materialer, som f. eks. pulver av wolfram-karbidlege-ring, kan anbringes på flater som har smeltepunkt på over ca. 315° C ved hjelp av den metode som er beskrevet i patent nr. 91 015. Surface coating of high-melting materials highly resistant to wear, such as e.g. powder of tungsten carbide ring, can be placed on surfaces that have a melting point of over approx. 315° C using the method described in patent no. 91 015.
I den nevnte fremgangsmåte blir en av et enkelt fluidum bestående brennstoff-charge eller en rask rekkefølge av brenn-stoffcharger av passende sammensetning som skal detoneres ført inn i et skyterør hvor den tennes slik at det opptrer en enkelt detonasjon eller en rekke av detonasjoner som følger etter hverandre med kort tids-mellomrom. I dette skyterør innføres det findelte faste stoffer, f. eks. pulver av wolfram-karbidlegering, på slik måte at disse materialer aksellereres av detonasjonene og de dermed følgende fenomener og slyn- In the aforementioned method, a fuel charge consisting of a single fluid or a rapid succession of fuel charges of suitable composition to be detonated is introduced into a firing tube where it is ignited so that a single detonation or a series of detonations occurs as follows one after the other with short time intervals. Finely divided solids, e.g. powder of tungsten carbide alloy, in such a way that these materials are accelerated by the detonations and the resulting phenomena and lightning
