The initial thickness of most molybdenum disulphide coatings has an important influence on the performance and life of the coating . The special case of sputtered films is considered in Chapter 10, and there is little information about thickness effects for in situ or transfer films. Many workers have investigated the effect of film thickness on bonded films, but, as was pointed out earlier, much of this work appears confusing, and sometimes contradictory, because of failure to understand and analyse the effects of running-in or burnishing on the consolidation and resulting structure of the films.

Various bond layers (i.e., W, Si, SiC, and SijN ) have also been tried on tool inserts to achieve strong bonding. The effectiveness of bond layers is very dependent on the exact composition and thickness of the bond layer material. Researchers have tried to replace Co with Cu in an electrochemical cell and reported... 

Figure 18.12 The relative strengths of oxoacids. A, Among these hypohalous acids, HOCl is the strongest and HOI the weakest Because Cl is the most electronegative of the halogens shown here, it withdraws electron density (indicated by thickness of green arrow) from the O—H bond most effectively, making that bond most polar in HOCl (indicated by the relative sizes of the 5 symbols). B, Among the chlorine oxoacids, the additional O atoms in HOCIO3 pull electron density from the O—H bond, making the bond much more polar than that in HOCl.

The following discussion will begin with a review of the basic theories of fracture mechanics, focusing on both the energy approach and the stress intensity approach. The application of fracture mechanics to adhesive joints will include the pioneering work in the area and test techniques which can be employed. Finally, consideration will be given to the effect of temperature, loading rate, adhesive bond thickness, and environment on fracture properties. 

Bascom et considered the effect of adhesive bond thickness. They observed an increase in fracture to a rhaximum with increasing bond thickness. Increasing the bond thickness further caused a decrease in fracture energy to a constant value. They attributed this to a dependence of fracture... 

S Adherend thickness effect on bonded joint strength for different joint geometries (adapted from Hart-Smith, 1974a). 

The effect of bond thickness on joint strength was the focus of two test series [2,42], One test series used steel adherends, while the other used aluminum adherends. Fabrication and test conditions for the two test series are summarized in Table 5. Thirty-seven joints with 303 stainless-steel adherends were tested, while 27 joints with 6061-T6 aluminum adherends were tested. The same triamine-cured...
