B. Rother et Km. Kazmanli, CHARACTERIZATION OF HARD COATINGS BY DEPTH-SENSING INDENTATION MEASUREMENTS - INDENTOR EFFECTS, Surface & coatings technology, 99(3), 1998, pp. 311-318
Depth-sensing indentation measurements were performed with Knoop, Vick
ers and Berkovich indenters on hard coating systems consisting of magn
etron-sputtered TiN, cathodic are-deposited TiN and (Ti,Al)N, as well
as magnetron-sputtered Zr-B-N. All coatings were deposited on hardened
high-speed steel. The measurements were evaluated by an energy-relate
d approach which provided the separation between coating, interface an
d substrate responses. The efficiency of the different indenters to th
e illustration of coating, interface and substrate effects was examine
d. In general, Berkovich-recorded results had the greatest potential f
or reproducible and reliable results. (C) 1998 Elsevier Science S.A.
