Nanoindentation, scratch and wear tests based on an atomic force microscope (AFM) were carried out to study the reliability of diamond-like carbon (DLC) films, deposited by electron cyclotron resonance microwave plasma chemical vapor deposition (ECR-MPCVD). The predictors for film reliability were given to investigate the resistance of DLC films to indent, scratch, and wear. Experimental results showed that the films at 64.9nm and 12.07nm exhibited better reliability than thin one at 2.78nm, 4.48nm. In addition, the reliability strength of films above 12.07nm went stable, and the films showed good performance of anti-indentation, and-scratch and anti-wear. Finally, size effect of nanoscale monolayer film was introduced to explain the reliability of nanoscale DLC films.

The viscoelastic behavior of isotactic polypropylene with ultra-high molecular weight(UHPPH) and broad molecular weight distribution(MWD), produced in the presence of Ziegler-Natta catalyst, was investigated by means of oscillatory rheometry at 180 and 200 ℃, whose loss modulus(G″) plots at 180 and 200 ℃ versus the natural logarithm of angular frequency(ω) present a pronounced maximum at 34.35 and 69.21 rad/s, respectively, and do not show a maximum peak at 0.01-100 rad/s for Ziegler-Natta catalyzing ethylene-propylene random copolymerization(PPR) with a conventional molecular weight and broad MWD. The fact indicates that the high molecular weight is responsible for a maximum peak of G″(ω) vs. lnω curves for UHPPH. This makes it possible to determine the plateau modulus(G 0_N) of UHPPH from a certain experimental temperature G″(ω) curve directly. For UHPPH, the G 0_N determined to be 4.28×10 5 and 3.62×10 5 Pa at 180 and 200 ℃, respectively, decreases with the increase of temperature and is independent of the molecular weight, which directly confirms reputation theoretical prediction that the G 0_N has no relation to the molecular weight.
