Industrial manufacturing linked to the mechanical and economic viewpoint of the mold steel grinding process using aluminum oxide wheel
(2021-01-01)
During the grinding process, cutting fluids are essential to guarantee the surface quality of the workpieces. On the other hand, these fluids can also compromise the efficiency of the process to view the alignment of ...
On the electrochemical behavior of Cu-16%Zn-6.5%Al alloy containing the β'-phase (martensite) in borate buffer
(2013-07-11)
In this work, the electrochemical behavior of Cu-16(wt.%)Zn-6.5(wt.%)Al alloy containing the β'-phase (martensite) was studied in borate buffer solution (pH 8.4) by means of open-circuit potential (EOC), electrochemical ...

Grinding behavior of VP50IM steel using green and black silicon carbide compared to aluminum oxide wheel under different feed rates
(2021-01-01)
Technological advances and the development of new products make it increasingly necessary to seek to improve production means to meet the growing demand for equipment and consumer goods. In this sense, the molds enable the ...
Estudo comaprativo da resistência da união esmalt/resina/metal. Efeito de resinas de fixação, artifícios retentivos e ligas metálicas.
(1990-12-01)
The purpose of this study was to compare the enamel/resin/metal bond tensile strength by using human canines, in which castings were bonded. These castings were obtained by Co-Cr or Ni-Cr alloys and showed four types of ...
Estudo experimental do uso de rebolos convencionais na usinagem do aço VP-50 utilizado na retificação cilíndrica, por meio de diferentes métodos de lubrirrefrigeração
(2016-01-01)
The grinding is a precise machining process, one of the most expensive steps in the manufacture of in-jection molds for thermoplastic. In grinding the grinding wheel abrasive tool is responsible for removal. The number and ...
Comparison of the shear bond strengths of conventional mesh bases and sandblasted orthodontic bracket bases
(2009-10-01)
This study aimed to compare in vitro the shear bond strength between metallic brackets (Abzil) with conventional mesh bases and metallic brackets with bases industrially sandblasted with aluminum oxide using three adhesive ...
Catalytic Behaviour of Mesoporous Cobalt-Aluminum Oxides for CO Oxidation
(Hindawi Publishing Corporation, 2014-10)
Ordered mesoporous materials are promising catalyst supports due to their uniform pore size distribution, high specific surface area and pore volume, tunable pore sizes, and long-range ordering of the pore packing. The ...
