Prášky ze slitiny titanu a molybdenu

práškové slitiny titanu a molybdenu enhance high-temperature strength and creep resistance for lightweight aerospace designs. This guide reviews TiMo alloy powder compositions, key characteristics, production methods, suitable applications, specifications, purchasing considerations, supplier comparisons, and pros/cons.

práškové slitiny titanu a molybdenu Typické složení

Molybdenum levels between 7% and 15% effective for high-temperature strengthening. Other elements like niobium, zirconium, and tin further boost creep properties.

Charakteristika a vlastnosti

Particulate nature, low oxygen content and tailored compositions suit alloy powder for additive manufacturing or sintering high performance components.

Výrobní metody

Plasma and gas atomization offer the best quality while being more expensive vs secondary routes like PREP and HDH.

Applications of TiMo Alloy Powder

Combination of high strength, low weight and corrosion resistance suits TiMo alloys with demanding environments like aircraft engines or offshore drilling.

Specifikace

AMPM (American Powder Metallurgy) Institute, IPS (International Powder Metallurgy Standards Organization) also cover various Ti grades.

Globální dodavatelé a cenové rozpětí

Pricing for 100+ kg batch. Premium for low oxygen and spherical powder. Larger quantities above 500 kg offer 20%+ discounts.

Výhody vs. nevýhody

TiMo powders enable new component designs and lightweight construction but using titanium alloys poses unique powder manufacturing and handling challenges.

FAQ

What particle size range is optimal for binder jet 3D printing?

Around 30 to 50 microns facilitates higher powder bed density and efficient liquid saturation needed to bind layers properly. Too fine powders hurt performance.

What causes contamination during Ti alloy gas atomization?

Oxygen pickup from any air leaks degrades powder purity hence the need for stringent process controls. Furnace parting agents and melt crucibles are other contamination sources requiring high purity consumables.

Why is high Mo content difficult to achieve in Ti based alloys?

Excessive evaporation losses of molybdenum occur above 25% levels during vacuum induction melting and subsequent remelting steps. Mitigation measures include covering melt pools or using cold crucible techniques.

Jak se má titanový prášek skladovat?

Inside sealed containers under inert cover gas or vacuum. Handled and stored to exclude moisture absorption which causes decrepitation and high osyggen or nitrogen impurity.

What are common defects when AM printing titanium alloys?

Porosity from trapped gas atoms, lack of fusion defects, residual stress cracking, unfused powder trapped inside enclosed volumes. Require integrated parameters optimisation accounting for scan strategy, energy input etc.

Závěr

Shrnutí, práškové slitiny titanu a molybdenu provide customized high temperature properties and corrosion resistance vital for producing next generation components across aerospace, energy and other demanding industries via powder metallurgy or additive manufacturing.
