OBJECTIVE
Tooling materials require special considerations in production and application. Students
will learn the metallurgical processes and applications in producing toolings.
UNIT I CLASSIFICATION AND MANUFACTURE OF TOOL STEELS 8
Classification - AISI system, production techniques – problems in melting - powder
metallurgy route, Refining methods like VAR and ESR - forming of tool steels.
UNIT II HEAT TREATMENT OF TOOL STEELS 10
Spheroidising – selection of quenching and tempering parameters – precautions - Effect
of retained austenite - Multiple tempering, sub-zero treatment and cryo treatment -
surface treatments - defects in tool steels - Over heated and burnt structures -
Decarburization.
UNIT III PROPERTIES AND TESTING OF TOOL STEELS 10
Mechanical propertiess of tool steels, strength, hardness and toughness – properties at
elevated temperature – microstructure - distribution of carbides - coating thickness –
micro hardness – adhesion and scratch resistance
UNIT IV ADVANCED TOOL MATERIALS 10
Sintered tungsten carbide tools - ISO classification – Uses of P, M and K grades –
cermet – ceramics, mixed and reinforced grades – cubic boron nitride – poly crystalline
diamond – manufacturing techniques – properties
UNIT V SURFACE TREATMENTS AND COATINGS 7
Sulphidising of tool steels – TiN coating by PVD – coating of carbide tools – mono and
multi layer coatings of TiC, TiN, Alumina and DLC by PVD and CVD processes -
selection of tool materials
TOTAL : 45 PERIODS
