Effect of tantalum content on the microstructure and mechanical behavior of cermets based on (TixTa1-x)(C0.5N0.5) solid solutions
(Elsevier, 2014)
Titanium-tantalum carbonitride, (Ti, Ta)(C, N), based cermets with different Ti and Ta contents were prepared using a mechanically induced self-sustaining reaction and then densified using a pressureless sintering process. ...

Hard Metal Production by ERS: Processing Parameter Roles in Final Properties
(MDPI, 2019)
Cemented carbide is a hard composite material, used widely in a variety of industries. The value of the global tungsten carbide market is expected to grow by 4.4% (compound annual growth rate) from 2017 to 2022. One of the ...

Ceramic dies selection for electrical resistance sintering of metallic materials
(Elsevier, 2019)
Processing metallic powders by electrical resistance sintering requires the use of insulating ceramics dies. Selecting the appropriate ceramic material according to the electrical, thermal and mechanical properties is a ...

Influence of temperature on the biaxial strength of cemented carbides with different microstructures
(Elsevier, 2018)
The effect of the temperature on the mechanical strength of WC-Co cemented carbides with different microstructures (grain size and binder content) was evaluated. Biaxial flexural tests were performed on three cemented ...

Improvement of the balance between a reduced stress shielding and bone ingrowth by bioactive coatings onto porous titanium substrates
(Elsevier, 2018-03)
Commercial pure titanium is known as good substitute for cortical bone tissue. Nevertheless, stress-shielding and the lack of osseointegration are still some limitations to solve. In this study, porous titanium substrates ...

Deposición sol-gel de hidroxiapatita bioactiva sobre titanio poroso
(ECIMED, 2017)
Introducción: el titanio y algunas de sus aleaciones son considerados la mejor opción para fabricar implantes permanentes, debido a sus excelentes propiedades mecánicas y resistencia a la corrosión en el ambiente ...

Processing and characterisation of cermet/hardmetal laminates with strong interfaces
(Elsevier, 2014)
Cemented carbides and cermets are potential materials for high speed machining tools. However, cemented carbides are not chemically stable at high temperature and cermets present poor fracture toughness. Novel cermet/hardmetal ...

Designing, processing and characterisation of titanium cylinders with graded porosity: An alternative to stress-shielding solutions
(Elsevier, 2014)
Bone resorption events and consequent failure of titanium implants are frequently related to stress-shielding problems, due to stiffness mismatch with respect to bone. This is a mechanical incompatibility problem, which ...

Balancing porosity and mechanical properties of titanium samples to favor cellular growth against bacteria
(MDPI, 2019)
Two main problems limit the success of titanium implants: bacterial infection, which restricts their osseointegration capacity; and the stiffness mismatch between the implant and the host cortical bone, which promotes bone ...
