This has particular advantages in the case of non-positive connections. In the known types of connection, a distinction is made between form-fitting, material-locking, frictional-locking or combinations of the connection types mentioned.<\/p>\n The transmission capacity of a frictional connection is limited by the design, the surface pressure and the material-specific coefficient of adhesion. However, through a targeted increase in friction, an increase in power transmission can be achieved without constructive changes to the component. This is made possible by the use of Diagrip\u00ae friction-increasing surface layers.<\/p>\n Diagrip\u00ae is an electroless nickel matrix with embedded diamonds of a defined size and concentration.<\/p>\n ![\"\"](\"https:\/\/www.cct-plating.com\/wp-content\/uploads\/2020\/12\/diagrip-schraegansicht.jpg\") ![\"\"](\"https:\/\/www.cct-plating.com\/wp-content\/uploads\/2020\/12\/diagrip-draufsicht.jpg\")
Diagrip – surface in oblique view and top view<\/p>\n
The layers can either be applied to thin foils made of steel or composite materials or directly to a component.<\/p>\n When using Diagrip\u00ae foils or direct coatings, increases in the transferable forces of up to 300% are achieved compared to the initial state. This effect is based on the penetration of the diamond particles into the opposing surfaces. This creates a micro-form fit between the main body and the mating body, which depends on the material, surface and surface pressure of the joint partners. This model is illustrated below.<\/p>\n ![\"\"](\"https:\/\/www.cct-plating.com\/wp-content\/uploads\/2020\/12\/diagrip-schaubild.jpg\") <\/p>\n

Some of the phosphorous is embedded in the coating during the coating process due to the procedure used, forming a nickel alloy layer (Ni-P).<\/p>\n The phosphorous content of the layer, and thereby the layer properties, can be adjusted in a targeted fashion.

Das hat besondere Vorteile bei kraftschl\u00fcssigen Verbindungen. Bei den bekannten Verbindungsarten wird zwischen formschl\u00fcssigen, stoffschl\u00fcssigen, reibschl\u00fcssigen oder Kombinationen aus den genannten Verbindungsarten unterschieden.<\/p>\n Die \u00dcbertragungsf\u00e4higkeit einer reibschl\u00fcssigen Verbindung ist durch die Auslegung, die Fl\u00e4chenpressung und dem werkstoffspezifischen Haftkoeffizienten begrenzt. Durch eine gezielte Reibungserh\u00f6hung kann jedoch eine Steigerung der Kraft\u00fcbertragung ohne konstruktive Ver\u00e4nderungen am Bauteil erreicht werden. Erm\u00f6glicht wird dies durch den Einsatz von Diagrip\u00ae reibungserh\u00f6henden Oberfl\u00e4chenschichten.<\/p>\n Diagrip\u00ae ist eine Chemisch-Nickel Matrix mit eingelagerten Diamanten definierter Gr\u00f6\u00dfe und Konzentration.<\/p>\n

Beim Verwenden von Diagrip\u00ae \u2013 Folien oder Direktbeschichtungen werden im Vergleich zum Ausgangszustand Steigerungen der \u00fcbertragbaren Kr\u00e4fte bis zu 300% erreicht. Dieser Effekt b asiert auf dem Eindringen der Diamantpartikel in die Gegenfl\u00e4chen. Zwischen Grund- und Gegenk\u00f6rper entsteht so ein Mikroformschluss, der von Material, Oberfl\u00e4che und Fl\u00e4chenpressung der F\u00fcgepartner abh\u00e4ngt. Diese Modellvorstellung wird in untenstehend verdeutlicht.<\/p>\n <\/p>\n Zum Einsatz kommen Diagrip\u00ae Schichten \u00fcberall da, wo effiziente und sichere Kraft\u00fcbertragung im Vordergrund steht. Aufgrund ihrer exzellenten Eigenschaften sind sie erste Wahl im Automobil- und Maschinenbau sowie in der Antriebstechnik.

Diese Temperaturgrenze limitiert nat\u00fcrlich auch das thermische Einsatzspektrum solcher Schichtsysteme erheblich.<\/p>\n Bei geeigneten Einsatzbedingungen zeigen die Chemisch Nickel \u2013 PTFE \u2013 Schichten einen sehr niedrigen Reibwert auch im ungeschmierten Zustand sowie eine deutliche Reduzierung des Stick-Slip \u2013 Effektes. Ebenfalls erw\u00e4hnenswert sind die ausgepr\u00e4gten antiadh\u00e4siven Eigenschaften der Schicht, die technisch vielf\u00e4ltig genutzt werden k\u00f6nnen.<\/p>\n <\/p>\n Querschliff Chem.
