Title:
PAD LINER FOR DISC BRAKING DEVICE
Document Type and Number:
Japanese Patent JPS62127525
Kind Code:
A
Abstract:
PURPOSE:To prevent the occurrence of cracks and separation of ceramics against a pad liner bend being repeated at the time of braking action, by forming each covered layer made up thermally spraying zirconia ceramics to the backside of the pad liner in a way of separating plural pieces. CONSTITUTION:Each rectangular top coat 14 made up of coating an undercoat 13 of nickel chromium on the backside 12a of a pad liner 12 and thermally spraying zirconia ceramics to an upper surface of this undercoat is formed in a way of separating plural pieces. In this connection, this top coat 14 is formed in 0.3mm in thickness by means of thermal spray after powder adding calcia (calcium oxide CaO), yttria (Y2O3), magnesia (MgO) or the like to powder of zirconia (ZrO2) or zirconia is masked on the backside 12a of the pad liner 12. Therefore, since bending quantity of the top coat 14 is reducible, the occurrence of cracks and separation is preventable.
