  1. 1. Toward predictive maintenance in surface treatment processes : A DMAIC case study at Seco Tools

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Martin Berg; Albin Eriksson; [2021]
    Keywords : Predictive maintenance; Industry 4.0; Data-driven maintenance; chemical vapour deposition; wet blasting;

    Abstract : Surface treatments are often used in the manufacturing industry to change the surface of a product, including its related properties and functions. The occurrence of degradation and corrosion in surface treatment processes can lead to critical breakdowns over time. READ MORE

  3. 2. Quality evaluation of PVD coatings on cutting tools by micro-blasting

    University essay from KTH/Materialvetenskap

    Author : Victor Berling; [2016]
    Keywords : Cutting tools; blasting; quality evaluation; PVD layers; Sandvik Coromant;

    Abstract : Sandvik Coromant in Gimo is in need of a good quality evaluation method of adhesion for PVD layers; since the existing testing method is located in Sandvik Coromant’s other location in Västberga. Different micro-blasting methods were investigated in this thesis and the results show that some of the methods could potentially be used for evaluation of adhesion, more specifically the wet blasting methods, M1 and M2.

  4. 3. Effect of texture and blasting pressure on residual stress and surface modifications in wet sand blasted α-Al2O3 coating

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Erik Ekström; [2015]
    Keywords : XRD; residual stress; alumina; Al2O3; blasting; annealing; activation energy;

    Abstract : Recently, wet sand blasting on coated cutting tool inserts has drawn interest to the tooling industry due to its positive effects on cutting performance and tool life. This performance boost has partly been attributed to the buildup of compressive residual stresses in the coating during the blasting process. READ MORE

  5. 4. Characterization of Hard Metal Surfaces after Various Surface Process Treatments

    University essay from Institutionen för fysik, kemi och biologi

    Author : Ali Hakim; [2008]
    Keywords : WC-Co; cermet; grinding; blasting; polishing; residual stress; surface roughness; surface deformations; cross section; adhesion;

    Abstract : The aim of this thesis is to investigate how material surfaces are affected by various surface treatments and how this relates to the adhesion of the coating. The materials that were studied were WC-Co and Cermets and the surface treatments used were polishing, grinding with coarser and finer abrasive grains, and finally wet blasting and dry blasting.
