Metallic materials

caractérisation des poudres métalliques

Characterizing physico-chemical or mechanical properties of metallic powders and sintered bearing materials


For a particular mechanical part produced by sintering, you want to know, check or qualify:
• characteristics of pure or mixed powder
• material properties after forming


Powders before sintering:
• SEM qualitative analysis with X-ray microanalysis (EDS method)
• apparent density
• grain size distribution
Sintered materials:
• macro and microstructure analysis (distribution, grain size, morphology, inclusions, porosity ratio)
• analytic mapping through x-ray microanalysis, qualitative and quantitative analyses
• hardness measurement (even light-load hardness measurement), hardness survey
• tensile test on probes
• break surface and coating microfractography (X-ray microanalysis, G=900 to 900 000)
• testing standards for sintered materials
• apparent density of sintered parts
• porosity ratio of sintered materials (with an accuracy of 1%)


• Cetim offers standardized or specifically adapted tests according to your demands
• we have specific laboratory facilities (SEM, vacuum coating machine, electronic sieving machine, densimeter)
• our multidisciplinary approach with, beyond powder characterization, various skills in counselling, support for material and process selection and testing (we own a test bench mounted on an adiabatic press)

Choix et caractérisation des matériaux

Les matériaux sont un enjeu primordial dans la conception de vos produits:
Lesquels choisir, selon quels critères, métalliques, composites, élastomères?
Comment les assembler ? Quels procédés de fabrication? Quels traitements leur appliquer ?
Autant de questions auxquelles les experts du Cetim vous apportent des réponses pratiques et argumentées, en les complétant si vous le souhaitez de prestations d'aide à la conception pouvant vous faire gagner un temps précieux dans la mise sur le marché de vos produits.
