Titanium Alloy Aerospace Parts Custom Service for High-Temperature Applications

Key Challenges in Titanium Aerospace Component Manufacturing

Manufacturing titanium aerospace parts involves critical technical challenges, including:

• Oxidation Resistance: Managing rapid oxidation at elevated temperatures above 600°C.

• Machining Difficulty: Overcoming titanium’s low thermal conductivity and high chemical reactivity during machining.

• Fatigue Strength: Ensuring reliable performance under cyclic loads at high-temperature conditions.

• Metallurgical Control: Preventing impurities and microstructural defects, critical for aerospace certification.

Detailed Titanium Alloy Manufacturing Processes

Vacuum Investment Casting

• Precision wax molds accurately replicate complex aerospace component geometries.

• Ceramic molds created by refractory coating; wax removal by autoclaving (~180°C).

• Titanium alloy casting is performed in vacuum furnaces (<0.01 Pa), preventing contamination.

• Controlled cooling at rates of ~40°C/hour reduces internal stresses, distortion, and microstructural anomalies.

Precision Forging

• Titanium billets are heated uniformly between 900–1050°C.

• Isothermal forging employs precisely controlled dies ensuring superior dimensional accuracy (±0.1 mm).

• Controlled cooling rates enhance microstructural integrity, strength, and fatigue resistance.
