Оборудование – Arcam Titanium CP (Grade 2)
ГлавнаяМатериалыArcam Titanium CP (Grade 2) 

General characteristics

The high strength, low weight ratio and outstanding corrosion

resistance inherent to titanium and its alloys has led to a

wide and diversified range of successful applications which

demand high levels of reliable performance in surgery and

medicine as well as in aerospace, automotive, chemical plant,

power generation, oil and gas extraction, sports, and other

major industries.

In the majority of these and other engineering applications

titanium has replaced heavier, less serviceable or less costeffective

materials. Designing with titanium taking all factors

into account has resulted in reliable, economic and more

durable systems and components, which in many situations

have substantially exceeded performance and service life

expectations.

Titanium is available in different grades, unalloyed or alloyed.

Special characteristics

Unalloyed Commercially Pure (CP) Titanium is available in

four different grades, 1, 2, 3 and 4, which are used based on the

corrosion resistance, ductility and strength requirements of the

specific application. Grade 1 has the highest formability,

while Grade 4 has the highest strength and moderate

formability.

CP Titanium users utilize its excellent corrosion

resistance, formability and weldable characteristics

in many critical applications.

Titanium Grade 2 is stronger than Grade 1

and equally corrosion-resistant against

most applications.

Titanium Grade 2 has numerous applications

in the medical industry.

Biocompatibility of Titanium Grade 2

is excellent, especially when direct

contact with tissue or bone is required.

Arcam EBM system

Applications

Titanium Grade 2 is typically used for:

– Orthopaedic applications, such as implants and prosthesis

– Airframe and aircraft engine parts

– Marine chemical parts

– Condenser tubing

– Heat exchangers

Powder specification

The Arcam Titanium Grade 2 powder has a particle size

between 45 and 100 microns. This limit on the minimum particle

size ensures safe handling of the powder.

Please refer to the Arcam MSDS (Material Safety Data Sheet)

for more information about the handling and safety of the

Arcam Titanium Grade 2

POST PROCESSING

Heat treatment

Hot Isostatic Pressing (HIP) is recommended

for fatigue-loaded components.

The following HIP parameters are

recommended:

– 920° C

– 100 MPa

– 120 minutes

Machining

Titanium Grade 2 parts manufactured

in the EBM process feature good

machinability and can be machined

as stock parts. The following factors

contribute to efficient machining of

Titanium Grade 2 parts:

– Low cutting speeds

– High feed rate

– Generous quantities of cutting fluid

– Sharp tools

– Rigid setup

Welding

Titanium Grade 2 may be welded by

a wide variety of conventional fusion

and solid-state processes, although its

chemical reactivity typically requires

special measures and procedures.

Microstructure

Titanium Grade 2 parts manufactured in the EBM process have a microstructure consisting

of fine α-grains, thanks to the rapid cooling of the melt pool.

The build chamber is kept at an elevated temperature throughout the entire build, and the

material thus comes out of the EBM process in a naturally aged condition.
