Since Vision was caught off-guard, he didn't have time to phase through the blade, and his synthezoid body began to malfunction. After Corvus Glaive's attack, Vision couldn't use his powers and remained badly wounded for the rest of the movie, which gave Thanos and the Black Order more freedom to confront the Avengers.
This is because Vision's potential is similar to Scarlet Witch, Strange, America Chavez, Hulk, Captain Marvel, Thor, and Monica Rambeau - it's predicated on self-belief. This is how Marvel keeps characters in Phase 4 of the MCU from being too overpowered and uninteresting.
In Infinity War, Vision didn't try to fight Thanos and sought with Wanda and the other Avengers to destroy the Mind Stone. They were afraid of Thanos' powers and were desperate to avoid the activation of all the stones and the cataclysm that would result from it.
Corvus and Proxima Midnight were paired up to retrieve the Mind Stone from Vision in Edinburgh, Scotland. Attacking Vision from behind with his spear, and stabbing him right through, Corvus downed Vision so that he could use the tip of his spear blade to remove the Mind Stone from where it was embedded in his head.

Marvel FINALLY Reveals Why Scarlet Witch and Vision LOST So Easily - AVENGERS INFINITY WAR
Could Vision beat Thanos?
This alternate has an argument, and perhaps the Thanos of its universe was somehow inherently weaker than the core MCU's, but there doesn't seem to be any scenario where the Sacred Timeline's Vision could ever defeat its Thanos, who had already harnessed five of the six Infinity Stones.
He simply wanted him dead at all costs because he was his biggest threat. As per the user, the director of Avengers confirmed that Thanos was most scared of Iron Man. “Not because of his strength, not because of his power, not because of his power, but because of his suit,” he added.
How hungry for power was Ultron that he was able to literally slice Thanos in half with the Mind Stone? Why couldn't Vision do that? Vision struggled to understand or control the infinite power of the Mind Stone. Ultron seemingly didn't. Ultron's Mind Stone feats are far above any of Vision's.
Moreover, Vision's power is from the mind stone and the only other two characters we know are stronger than Thanos - Carol and Wanda - also have infinity stone-based powers, so that could say something about his weaknesses/their power levels.
Many characters need to become underpowered, such as Thor, Superman, and The Hulk when working with a team to ensure that everyone receives iconic moments. The Marvel Cinematic Universe depends on the representation of many diverse characters to accomplish this, and lessening Drax's powers is crucial to this.
"We just didn't know what to do with him. We were like, 'What, this big powerful character. What we do with this big powerful character? '" Despite the mixed reception from fans, the brothers have no regrets about their decisions with Hulk.
Thor essentially 'gives birth' to Vision, which means there's part of him – or more specifically part of Mjölnir – in Vision, which gives him the ability.
Vision wasn't made in 2014, which is when Nat, Clint, Nebula, and Rhodes went. It's the same reason why Heimdall, Loki and Gamora also didn't came back by Hulk's snap! They died in Infinity War but not got snapped out of existence...
Vision is killed by Thanos when he removes the Mind Stone to complete the Infinity Gauntlet in order to initiate the Blip. Years later, Vision's body is reactivated via Wanda's magic, albeit initially without his memories and with a different appearance.
In the comics, Wanda is far more powerful than Vision. The movies only scratched at the surface of her powers. In the movies, Vision didn't fully understand the scope of the power contained within his stone.
Vision's corpse was taken by S.W.O.R.D. and disassembled in an attempt to weaponize his remains. Vision's body was then reassembled in a white form and reactivated through a sample of Maximoff's Chaos Magic, and was employed by S.W.O.R.D. as their sentient weapon.
The Vision is quite strong as well - he can rip straight through a mutant-hunting Sentinel's armor - but not nearly as strong as Thor. The Vision's only hope in winning this battle rests with his unique ability to control his body's density.
In Avengers: Age of Ultron, after being partially destroyed by Ultron, J.A.R.V.I.S. is given physical form as Vision, physically portrayed by Bettany. Different versions of the character also appear in comics published by Marvel Comics, depicted as AI designed by Iron Man and Nadia van Dyne.
Though usually paired against beings like Adam Warlock or Drax the Destroyer, the Mad Titan has no shortage of archrivals to choose from. But the one being Thanos hates more than anyone is the Merc With A Mouth himself, Deadpool – a rivalry that MCU fans are likely going to miss.
The fear of losing Pepper, or his best friends like Happy, Steve Rodgers, or Rhodey, was something Tony wouldn't be able to live with and was the primal force pushing him to defend the Earth. So when the first members of the Black Order landed on Earth, Tony's biggest fear was coming to life.
While audiences never got to see Quicksilver at full power, super-speed is one of the best abilities a hero can have when facing an enemy like Thanos. With enough training, Quicksilver would have been more than capable of defeating Thanos when he finally arrived in Infinity War.
