High-velocity flame spraying of WC-Co cermet was applied on a tool steel substrate (JIS: SKD5). After the specimens were heated in air or vacuum, edge-indentation tests of the specimens were carried out to examine the change of delamination energy. For the specimens heated at 773K in air or vacuum within 144ks, delamination load did not change. When the heating temperature was 873K and hold time was longer than 144ks, the delamination load decreased. Delamination area decreased when the holddoi:10.2472/jsms.48.1065 fatcat:bu3awmefszhhrffgxljzfkemvi
