Influence of surface integrity on bonding process

Abstract

Müller M., 2011. Influence of surface integrity on bonding process. Res. Agr. Eng., 57: 153-162.Adhesive bonding technology is successfully applied partly in the primary production, partly in the renovation in various fields of human activities. This fact emphasizes the importance of the partial factors research, which influence is essential for the quality, reliability and necessarily the usable life of bonded joints. The mechanical preparation of bonded surface is a varied process which influences directly the resultant bonded joint quality. The aim of the bonded surface mechanical preparation is the adhesion improvement in the adhesive -adherend interface. For mechanical preparation we use tools of defined cutting edge, by means of which we get the uniform surface texture, e.g. by milling. On the contrary such methods are more often used when the uniform surface cannot be reached. Shot blasting and grinding are significant representatives of these methods. The manual grinding can be significantly applied mainly in the agriculture. The absence of connected areas availability for the mechanical tooling and impossibility of their work clamping are the reasons for that. The breakwater in the sprinkler cistern restricting the liquid motion is the example.

Analysis of Physical Effects in Cutting Machining

“…Iron-carbon alloy; the content of carbon approximately 3 %, and other elements are silicon (2-2.5 %), manganese (0.5-0.8 %), phosphorus and sulphur. Carbon is eliminated in the primary form as lamellar graphite [11,12]. Cutting Force Scanner.…”

Effect of Abrasive Waterjet Peening Surface Treatment of Steel Plates on the Strength of Single–Lap Adhesive Joints

“…Widespread use and development of adhesive bonding technology involves continuous search for new solutions to improve the bonding process and increase strength of bonding. As it has been shown in many studies, the method of surface preparation and degree of its geometric surface development has a significant effect on strength of the adhesive joint [3,4,7,8]. Adequate preparation of the bonding surface guarantees an increase in adhesion forces, which are responsible for the adherence of the adhesive to the adherend material [6].…”

Research on Mechanical Properties of Single-Component Epoxy Designed for Bonding of Structural Joints

“…The production process in various industrial sectors divers, but usually has one common element and that is forming a bond (Müller 2011).…”

“…To obtain a proper and strong bonds, it is essential to start with a clean surface of the adherent because the surface treatment of adherents before bonding is one of the most important operations in the bonding process (Messler 2004). If there is no surface preparation satisfactorily implemented, the bond inevitably and unpredictably fails on the surface of the contact material and the adhesive (Müller, 2011).…”
