Effect of Surface Preparation

Cotter and Kohler likewise concluded that anodized surfaces produce the most durable adhesive bonds to aluminum. Their study included a comparison of the effects of using bare and clad alloys. In humid conditions, no significant difference was observed in the durability of chromic acid-anodized specimens prepared from the different alloys. In a corrosive environment, however, specimens prepared from the bare alloy proved to

A number of attempts have been made to develop an alkaline peroxide anodize for titanium. However, the process requires careful control in order to provide durable adhesive joints. A recently developed sodium hydroxide anodize treatment appears to provide excellent durability and easy process control. The wedge test was used with exposure times of up

Although numerous studies (1-3) have described work aimed at establishing criteria for the durability of adhesive joints, a thorough understanding of effects of the chemical and mechanical properties, on the durability of adhesive bonds is lacking. More specifically, the effects of surface preparation and dynamic loading, especially under environmental service conditions, has not been explored in detail for automotive structures. In this paper, a description of the effects of environment on the durability of adhesive bonds is presented. Particular attention is given to...

Two data sets highlighting the effect of surface preparation are shown in Figs. 6 and 7. Here we have compared FPL-etched alloys to H PO -anodized aluminum alloys. For AF-147 the durability at each load level is substantially increased by using H3P0 -anodized adherends.

Before actual bonding, the subjective water-break test or the quantitative and objective contact-angle test may be carried out. After bonding, the effectiveness of surface preparation may be determined by measuring the bond strength and determining the mode of the failure of the adhesive joint.

Data drawn from five separate test series were used to assess the reproducibility of /tac measurements and to examine the effect of surface preparation on K c values [3]. Table 6 lists fabrication parameters for the five sets of adhesively bonded butt joints. All had 6061-T6 aluminum adherends, and they were fabricated and tested over a period of 15 months. The aluminum bonding surfaces of most joints were lightly sandblasted (60 grit alumina oxide at 40 psi), although the surfaces of some joints in Sets 1 and 2 were left in the as-machined condition to assess the effect of surface roughness. The roughness of the as-machined and sandblasted...
