Abstract

SURFACE METROLOGY A Report on the Fourth International Conference on the Metrology and Properties of Engineering Surfaces, National Bureau of Standards, Gaithersburg, MD, April 13-15, 1988 carbon black agglomerates in rubber, a family of materials that might normally be thought of as too soft for reliable characterization by stylus. Inadequate dispersion leads to reduced product life and other detrimental effects in rubber products. Figure 1 shows the stylus in contact with such a rubber surface. The presence of the agglomerates is evidenced either by discrete peaks in the stylus profiles or by valleys left when the material is separated during the cutting process.
