  1. 1. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Muhammad Hashir Zaheer; [2023]
    Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

  3. 2. Chip Management in Milling and Drilling of Ductile Cast Iron

    University essay from Lunds universitet/Industriell Produktion

    Author : Alexander Jönsson; Giacomo Aliboni; [2023]
    Keywords : Chip Carryover; Chip Management; Ductile Cast Iron; Chip Removal; Chip Asportation; Milling; Drilling; Technology and Engineering;

    Abstract : This paper presents a comprehensive cross-functional analysis of machining operations for ductile cast iron components in the automotive industry, focusing on the problem of chip carryover and its impact on downstream processes. The research aims to understand the role of machining and identify the source of the issue, by analyzing different machining sequences and the chips that affect the final product or subsequent production stages.
