Adhesion Measurement of Thin Films, Thick Films and Bulk Coatings. Edited by K. L. MITTAL, American Society for Testing and Materials, Philadelphia, 1978. 402 pp. $39.25. Precise and meaningful data are required for understanding and solving bonding problems and for developing reliable, stable bonded structures. Often tests of bond strength selected for convenience or lack of more suitable methods do not give the needed information. Equally important but more frequently unrecognized is the fact that arbitrarily selected bonding conditions may give meaningless results (unless using those fixed conditions is a specific requirement). The editor could have contributed significantly through critical discussion of these basic factors. His introduction and "recent progress," however, add little. The other five general papers provide in part what the editor missed. Good's discussion of failure locus is essentially a shortened, somewhat updated version of his earlier work. Unfortunately the late Dr. Bikerman's contribution offers nothing new and lacks the crisp (if biased) insight of his earlier papers. I regret that in what was one of his last papers he did not respond to the many recognized criticisms of his views. Baun provides an overview of some of the new methods for investigating the nature of interfaces, and Mattox a prespective touching on many of the factors influencing or controlling bond strength. Bascom demonstrates the use of the fracture mechanics approach and Murr, the use of sessile drops and zero-creep methods for estimating surface energies in metal/ceramic systems. The volume treats a relatively broad range of techniques covering several interesting variations of seven basic methods: impact or accelera-
Air Sampling Instruments for Evaluation of Atmospheric Contaminants, 5th ed. American Conference of Governmental Industrial Hygienists, Cincinnati, Ohio, 1979. The kinds of instruments available for air sampling are many, utilizing diverse phenomena and producing results which are often at variance with one another. Sampling methods for collection of aerosols are necessarily different from those used for sampling gases and direct reading instruments are Journal of Colloid and lnterfoce Science, Vol. 72, No. 1, October i5, 1979

tion (ultrasonic and laser spallation), cantilever (double-cantilever and "pull-down"), tension (conical head and I-beam), shear (ring shear, plate shear, and pullout), peel, torsion, and scratch tests. Also included is a practical test (for interface quality and stability) based on resistance to etchants. The major contribution of this work lies in the detailed descriptions of materials, procedures, advantages, and disadvantages provided by most of the authors. A major weakness is lack of such information from the others. The volume seems to have been compiled rather than edited. There are no indications of emending. There is unnecessary duplication. In two of the papers, data important to assessment of the work were referred to but not included. Considering the volume is published by ASTM, it is surprising that only a few authors used preferred SI units, and three used engineering units only. If the introductory contributions by the editor were inadequate his summary is redundant. If there were a need for a summary it would be to provide a learned critical assessment of the contribution of this work. That is completely lacking. While there is much to criticize, many readers will find the book useful. J. R. HUNTSBERGER

Even the method of collection of an air sample can be extremely important and can vary depending on where the sample is to be collected. Selection of the proper sampling method for a particular application is essential. This book is an excellent reference book for anyone dealing with air sampling.
